The miserable thing about being insomniac is that you are in fact bone tired--but you can't sleep. You wake up at 3am and can't get back to sleep, so you turn on the light, and try to read, but you're so exhausted your eyes cross and you're not retaining any information. So you turn off the light and curl up: but you can't stop your mind from racing. So you turn on the light and try to read ...
I took up yoga to deal with this. And meditation. I cut out caffeine after 1pm. I make before bed to-do lists to rid my mind of its calendaring demons. I restrict my academic writing and research to daylight hours so I don't get too excited before bed. I dim the lights, I drink herbal tea, I take prescribed sleeping meds and off-label pharmaceuticals on an as-needed basis. Sometimes I self-medicate with Forty Creek Copper Barrel Reserve, 1 oz. Or a dry martini, right before bed.
But sleep often eludes me, still.
Insomnia is an invisible disability. I find it impossible to do creative or scholarly work when I'm sleep-deprived. I can grade (slowly, inefficiently) and I can go to meetings (groggily) and write emails (proofreading twice). Then I feel terrible about not working, which leads to more insomnia, and even more not working.
Insomnia is incredibly humbling. Neither brute force, nor will power, nor good intentions, nor even some pretty good drugs can make sleep happen--the links between mind and body are powerful and intense and won't be denied. This is a good lesson to remember.
I suspect many of you suffer from insomnia as well. What do you do to manage? Right now I'm trying to be kind to my insomnia, to ask it what it is trying to tell me, what part of my life is not fitting well right now, and how I might be kinder to myself to resolve it. I'm trying to eat better and not drink too much, to get enough exercise, and ask my family to let me nap when I need it.
But it's important to note that one of the reasons I have insomnia is because of this job, this life of the mind: sometimes my ideas scare me so much that I can't let them go, for fear of losing them. Sometimes, the deadlines pile up and I worry I won't meet them. Sometimes before talks I worry for weeks not about not being ready but about not being good enough. Since I've taken up my administrative role in my department I worry about the drip drip drip of forms to sign, things to check up on, meetings to remember to attend, deliverables I've forgotten I've promised, hard cases, tough decisions, all the emails. The work is not bounded by location or time; it is never done, and it could always be done better, or more or faster. My insomniac periods peaked when I was on the job market, the year I came up for tenure, and the year I began my administrative job. The academy always wants more, and we A+ students will always try to give more, even if we don't have it, and feel like we're failing.
