"generic doxepin (25mg) helped wonderfully with my insomnia...at first. it&#039;s great for short-term use because it truly lets you sleep *as long as you want*.  however after about 3 weeks, i starting developing tolerance and began taking 50mg every night.  a month later and i was up to 75mg.  in months 4 and 5, i was taking 100mg every night.  with the increased dosage, so increased the unpleasant side effects (&quot;hangovers&quot; in the morning).  when i switched to a stronger sedative, i suffered withdrawal in the form of middle-of-the-night awakenings for several weeks.

one other note - it&#039;s not fast acting like newer drugs so i had to take it 2 hours before bedtime in order to feel sleepy."
