alcohol withdrawal
"I have been a heavy drinker for many year, substituting Vodka for lunch and dinner. After I found I could barely write due to shakiness, I went to my doctor.  He prescribed Naltrexone, Camprial, and Librium.  It has worked wonders!  So far, no urge to drink, no side effects, and sleeping better than I have in years.  (I must admit that I am somewhat tired, but so what!)  The fog is slowly beginning to lift and I am feeling joy once again.  If I can do it, anyone can!  This is a life saver."
