insomnia
"My insomnia started as a teenager.  I started out with lunesta.  It had no effect.  Next came the Ambien which caused me to sleep walk essentially.  *one of the most dangerous drugs on the market*.  I started contemplating why I couldn't sleep every night and it went along the lines of an anxious curiosity.  Thinking to myself I wonder what the molecular structure of that plaster looks like.  So I asked to try something more anxiety based and less sleep aid based.  I have been taking it periodically when required for the past 10 years with breaks in between.  2 mg will knock me out hard but 1-1.5 mg is a pretty good dose to just relax me.  I've never been very dependent, no withdrawals, and I have never built up a tolerance to it."
