insomnia returns

My brother is supposed to be here at about 8 A.M. tomorrow morning. So I took a couple of Benadryl at about 9:30 to make sure I got my full night's sleep. An hour later, still wide awake, I took another Benadryl. Later a Valium because my restless legs were (I thought) still preventing sleep. Another hour, and I broke down and took a Xanax. Now it's a quarter of 2 A.M. and I'm foggy in the head but still cannot get to sleep.

I guess I'll try to sleep on the couch. I can always nap on the couch during the day, why not at night?
