insomnia
"Started taking this drug after having trouble dealing with anxiety at bedtime, and I honestly could not have asked for a more effective drug or excellent results.  Unfortunately finally built up resistance to 3mg; at that point I had to stop taking it and did so the wrong way.  Went cold turkey and did not sleep for three nights in a row even though I was taking Benadryl x3 and a Rozerem. Been trying different non-sedadting (hypnotic/non-benzodiazepine) sleep aids and have found nothing close to Lunesta yet."
