"i have had insomnia for years. in 1991 i had surgery for ovarian cancer. the chemo made me very nervous.  my dr. prescribed this medicine and it worked great.  since then, i have continued to take.  i have worked in a health food store for years and have tried all the natural supplements.  so far this is the best and safest medication i have taken.  i usually only need 1 mg. at night.  i also have irritable bowel syndrome and fibromyalgia and it works great for it also.  my dr. said this medicine is much safer than over the counter sleep aids."
