insomnia
"I have had trouble staying asleep for several years. No problems falling asleep, but most nights I wake up around 3 or 4AM (five hours into my sleep) and from that point forward I sleep fitfully. I tried Silenor (actually generic Doxepin) for about three weeks. It seemed to help a bit for the first few days, but after a few weeks I noticed no improvement beyond no medication. First few days I experienced about a 1-2 low grade hang-over. The most notable part of the experience was the very vivid dreams I had. They were not nightmares, but they tended to be disturbing and about mundane aspects of life. Things like being late for appointments, dealing with unwanted guests, arguments with friends, etc."
