"i have had severe insomnia since being diagnosed with fibromyalgia in 1999.  i will be awake all night without meds.  ambien was the worst as far as side effects--should be off the market.  i now take 2 mg of clonazepan and 10 mg of doxepin.  still takes me hours to fall asleep, but at least i do.  best i&#039;ve taken so far.  only side effect for me is that i don&#039;t feel low blood sugars until the 40&#039;s (i&#039;m diabetic).  so i check my bs often.  have not slept through a night since 1998.  hoping to increase dosage next doctor visit."
