"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."
