Long story short: 40 year old male, before late December of 2015 could count on two hands the amount of times in my life I'd had trouble falling asleep. For the past 3 weeks, I've been unable to fall asleep for 2-3 hours every night. And I can't figure out why. And nothing seems to help.
I don't smoke. I drink one coffee a day, always before 1 PM, and my bedtime is around 12:30-1 AM. I am very physically active and exercise every day. I don't eat late meals. Prior to this, I am not under any new external stress. My relationship is really good and we've been sleeping together in the same bed for years. About a week before the new year, I started having occasional trouble falling asleep. It's now snowballed and I am lying awake every night for 1-3 hours. I still manage to get 4-5 hours of sleep, which I know is not terrible relative to what some other people deal with, but it's a lot less than I'm used to and I walk around feeling exhausted all day.
I have tried a number of solutions. Started with chamomile tea in the evening. Then, tried Valerian root. Then, Ashwagandha. Melatonin. Now, magnesium citrate. Have tried guided meditation. Counting sheep. Doing visualization. Replacing negative thoughts about sleep with positive thoughts. Everything I could find. Pot used to really help me any time I felt exceedingly stressed and/or couldn't sleep, but now, when I try it, I just feel awake and high.
Eventually went to the doctor. Heart and thyroid function are normal. He first gave me Ambien 10 mg and told me to try it for 7 days. It seemed to help the first two nights, and then didn't, at all. Yesterday, he switched me over to Xanax 1 MG. I took it and felt absolutely nothing in terms of euphoria, anxiety relief, or drowsiness.
I know that at least part of this now is mental - I'll sometimes nod off on the couch, but then, when I go to my bed, I'm wide awake. My bedroom is dark and quiet, and I slept in it fine for months before all this started. I'm practicing good sleep hygiene - taking time to wind down before bed, not going to bed until I feel drowsy, etc. And still, every night, I lie there exhausted but unable to drop off into sleep.
I'm at the end of my rope, here. I don't know what else I could possibly do. I don't want to stay on Xanax very long because I've read all kinds of bad things about what happens if you do. I know a big part of this is breaking the mental cycle of going to bed and worrying about going to sleep, but none of the techniques I've found for dealing with that have helped me. I'm tired of feeling exhausted and sick every day.
Help?
