Last night, my back spazzed out on me - not horribly, but enough to make me say, "what the - - did I do now?" By bedtime, it was a bit better. Went to bed, couldn't sleep, back a little tight but not crazy-tight, 3 am turned off the alarm.
Back in bed, wondering...what is it? The fact that someone's coming over today who's never seen my embarrassing house? No, I'm not that concerned. Hope it's not the Tramadol that's been helping so much, I've been doing great with it. Tossed and turned all night, finally in and out of bizarre dreams, very unpleasant ones. Maybe got a couple of hours sleep.
Groggy morning, bleh, sit down at the computer and there's my half a Klonopin sitting on a pad of paper. How I managed to not take it along with my Nortriptyline like I do every night, I don't know. But at least the mystery is solved.
Thanks for letting me vent about my petty problem!
