Kam drove me to the doctor yesterday; the doctor prescribed me some Ambien. (I tried Sonata once, years ago, and it worked well once or twice and then stopped working entirely; anyway, the doctor said they no longer prescribe Sonata, though he didn't say why and I was too exhausted to ask.)
Kam took me to the drugstore, where I picked up the prescription. We came home, had some food (yay chicken soup!), watched some West Wing, and then it was time to pick up Jim at the airport. Luckily, Kam drove; I probably wouldn't have been safe driving.
Came back, chatted a little, then I remembered the pharmacist had said to take the Ambien an hour before bedtime, so I took one, sometime around 10 p.m. I started feeling groggy within a few minutes, and then my memory stops completely. I woke up a little disoriented in bed around 4 a.m.; went back to sleep, woke up a couple hours later, went back to sleep, woke up around 8 or 9, eventually decided it was time to get up.
I don't feel as thoroughly rested as I would've hoped, and the stuffed-up nose and sore throat remain, and an occasional cough has developed. But I no longer feel entirely incapable of coherent thought, which is how I've felt for the past two days. I'm probably still not entirely on top of things; I suspect my judgment and decisionmaking capabilities, never that strong to begin with, are still on the weak side. I'll probably try to avoid making any big life decisions in the next couple days. But yeah, big improvement over yesterday and the day before.
I'm hoping that this has gotten me past the sleep problem and I'll be able to sleep tonight without the Ambien. Or maybe I'll try a half-tablet tonight; the pharmacist said it affects some people really strongly at first, and suggested a half-tablet, but I thought "I want it to affect me really strongly!"
Anyway. It's a big relief to have finally gotten some sleep.
Thanks to all who've proffered advice and sympathy, and thanks especially to Kam for driving me around, doing dishes, and generally taking care of me. And to everyone for putting up with me being alternately moody, grumpy, snippy, and incoherent lately.
