Doxepin
"I was prescribed 10mg pills for insomnia; I fall asleep readily, but can't stay asleep for more than 2 hours at a time. That's partially due to having dry mouth; drink something, have to go to the bathroom, wake up with a dry mouth, drink something, go to bathroom - vicious cycle. I'm awake for about 15 minutes after each episode.
I took doxepin for 4 days out of 9. I started having very vivid dreams, to the point that I did not know what was actually real the next day. I also started feeling "who am I?", "where am I?","what am I doing here? - in other words, very disoriented. I had walked to a neighbor's house to get paperwork for the Civic Assn. I truly had no clue what the lists were, or what they were for. I glad I made it back home."
