That was my problem with the Trazadone. Nasty taste in my mouth the next day. The hangover feeling was kind of bad too.

I dont take sedatives full strength. Had some Ambien in the mid 90's, and the first night, I took it full strength. Had a scary hallucination/dream where the room was bright red, and the tv was crawling across the floor, dragging the tv stand behind it. It was a little freaky.

I havent had that problem with the Amitriptyline yet. That's actually helped improve my dream content. Had some rather interesting and entertaining dreams on the Amitriptyline, and I only take 1/4 of a pill, maybe 1/2 if the insomnia is really strong.
