That's been about the story of my life for the last few months.
At first, I passed it off as stress. I made a lot of big changes in my life all at once - leaving home, living on my own, getting married - and I kind of figured that was to blame. But it's been months now. Things have settled down, I've smoothed out a lot of issues, and now my only real source of stress is having to cope with a crazy family, which is nothing out of the ordinary for me.
I've tried everything. We've moved everything electronic out of our room and tried the whole, "Use the bed for sex and sleep only" approach. Didn't work. I cleaned our room keeping in mind that a lot of places suggest that a clean room makes for an easier time sleeping. No help what so ever. I went out of my way during the day to do things that would make me extra tired - mostly, exercising for a bit longer than normal. Nope. So then I resorted to taking a few Benadryl. Normally, the shit knocks me right out. No go. I spent a few hours staring at OTC sleep aids (which, by the way, generally all contain the same ingredient in the same dosage). I even picked a few up. Nothing. I've tried meditation, drinking "bed time" tea, lavendar and chamomile soaps and lotions formulated for bed time, soothing music, classic relaxation techniques... Anything. I've tried every bullshit remedy I can get my hands on, and nothing is helping me.
My mind doesn't race or anything. In fact, the most complex train of thought I'm usually capable of is, "Gee. My ceiling looks nice tonight. Perhaps I'll step out for a smoke. Oh. The stars are pretty. [insert elevator music]"
I guess I should be seeing a doctor soon.
