Sleep restriction and
stimulus control were the main behavioral interventions for tackling my insomnia, but they don't call the treatment
cognitive
behavioral therapy for nothing! A large portion of it involved
addressing the thoughts and fears that were contributing to my lack of
sleep.
It's easy to follow a bunch
of rules: Get out of bed at the same time every morning! Don't go to
bed if you're not sleepy! Don't stay in bed if you can't sleep! It's a
lot harder to change your unconscious responses and entrenched beliefs,
but these were probably the biggest factors that were keeping my
insomnia alive.
"I can't sleep."
"Why am I still awake?" "I have forgotten how to sleep." "OMG, the sun
is rising in 2 hours and I still haven't slept!" "What if I have fatal
insomnia?" Thoughts like these are not restful
thoughts! They are the kind of thoughts that get your your mind racing
and your heart to follow suit, until your entire body is on high alert.
Learning
to recognize these thought patterns and how they were sabotaging my
sleep was vital in my recovery. And the first step was gaining a basic
comprehension of how sleep works. I don't want to pass myself off
as any kind of expert, but here's the gist of what I learned, told
maybe just slightly more dramatically than how I learned it.
Sleep is basically controlled by a constant, epic battle between two forces: sleep drive and arousal. Sleep
drive is, in essence, a measure of how badly your body needs to sleep.
When you first wake up in the morning, your sleep drive is low because
you're well rested, and it builds up over the course of the day until
you're (normally) ready to fall asleep again at night. Sleep drive is
controlled by one factor and one factor only: how long you've been
awake. Longer wakefulness = more sleep drive, and enough sleep drive
always leads to sleep eventually.
However,
sleep drive doesn't operate in isolation. It can be suppressed by the
other major player in the sleep arena: arousal. No, I'm not talking
about sexual arousal—come on guys! It's just a word that means...
well... the opposite of sleepiness. Lots of factors can contribute to
arousal—being uncomfortable or in pain, chemical stimulants, excitement,
emotional distress, and fear. When you have enough mental arousal, it
overrides your sleep drive, and you will not be able to sleep.
Arousal
typically has an edge over sleep drive, because you need to be awake in
order to respond to potentially dangerous situations. However, in the
mind of an insomniac, sleep itself gets conflated with a dangerous
situation (because of all the conditioning that has
linked bedtime with worry
and wakefulness). Consequently, the insomniac develops more fear and
worry about sleep, experiences more nighttime arousal, and sleeps even
less!
It seems so
obvious when I see it explained like that, but it was a breathtaking
revelation to me when I was still in the thrall of insomnia. My sleep
wasn't some magical entity that had decided to abandon me; I had driven
it away with my own thoughts! In order to sleep well again, all I had to
do was replace my negative and erroneous beliefs with reassuring facts,
and gain control of my feelings about sleep.
Here are the facts that helped me turn the corner on insomnia.
This
is the tagline on all of Martin Reed's Insomnia Coach videos, and with
good reason. When I was struggling with insomnia, I worried extensively
about my ability to sleep. At times, I thought I really had lost it
entirely. This was of course completely silly, because I did sleep,
every night. Maybe for only one or two hours, and maybe only with the
aid of some substance or other, but I always did fall asleep. This
should have clued me in to the fact that I hadn't lost my ability to
sleep, but I needed to hear it in words. And I did. At the height of my
insomnia, I would watch a
Sleep Snippet video every evening, just for the reminder.
2. You can't force sleep.
Learning
how sleep drive is the one and only thing that can make a body sleep
was an immense weight off my back. I was immediately liberated from all
the time-consuming
practices I'd adopted
to help me sleep. All that nighttime yoga, the binaural beats, the
experiments with meals and their timing, the neverending guided
meditations and breathing exercises—I could throw them all away, because
none of them were going to make me sleep! They might help me relax a
little, and they certainly weren't harmful, but they weren't going to
make any significant difference. All I really needed to do was wait to
sleep until my body was ready for it.
This
is another direct quote from Martin Reed, but I found it incredibly
reassuring. In the epic battle between sleep drive and arousal, arousal
may take the upper hand for a while, but even chronically sleep-deprived
folks experience micro-sleeps, and even hardcore insomniacs crash after
several days awake. It's impossible to go without sleep forever, and
once I internalized that fact, I was able to go to bed with confidence
that eventually I would fall asleep again. In the past, I had felt like I
was at the mercy of my insomnia, but now I realized, my insomnia was
only just barely holding its own against my indomitable sleep drive.
4. You're probably sleeping more than you think you are.
One
fact (backed up by research) I keep hearing is that "normal" sleepers
generally overestimate how much sleep they get, whereas insomniacs
tend to underestimate it. I found
a video
explaining that if you are woken up during stage 2 non-REM sleep, you
only have a 50% chance of believing that you were asleep at all! Knowing
this, I could recall plenty of nights when I thought I hadn't slept,
but time had seemed to pass much too quickly for me to have been awake.
Another sleep expert said that if you can't tell whether you were asleep
or awake, you were probably asleep. Deciding to believe that I'd
actually been asleep during those ambiguous times made me feel a lot
better! Even if I wasn't sleeping
great, I was still probably getting some amount of much-needed rest.
5. Going without sleep is not a catastrophe.
This
one walks the line between fact and belief, but it's rooted in logical
analysis and an evidence-based conclusion. One of the things I was
encouraged to do in my sleep training is interrogate my beliefs
about sleep. For example, when I was lying in bed at night and starting
to panic over the fact that I was still awake, I was supposed to ask
myself things like, "What is the worst thing that could happen? What is
the most likely outcome?" When I put my thoughts to the test, I realized
the worst-case scenario was that I would not sleep at all and start a
run of several nights of no sleep, resulting in a mental breakdown and administration of benzodiazepines in the ER (it's a story oft told in my insomnia support group). Honestly, I think that would
be a catastrophe—but it had never happened to me. It was much more
likely that I'd at least sleep a couple of hours once I calmed down, and
the sleep deprivation from this night might even make it easier for me
to sleep the next night.
Arming
myself with these facts had an almost immediate positive impact. I no
longer stressed about sleep all day long. Once I stopped thinking about
sleep all the time, I also stopped feeling tired all the time. So even
though I was sleeping much less than I ever had before, I still felt
pretty energetic during the day. It was a great shift, and it helped
give me the emotional strength to tackle the greatest challenge
yet—adjusting my attitude.
But I'll save that topic for another post.
