anxiety
"Suffering 16 years ago from PTSD after being told in hospital that I only had 30 mins before I would die, I was a wreck when I came home and lived in fear and terror, shortness of breath, uncontrollable shaking, extreme nausea, body aching all over, doctor and specialist visits - had every test known to the medical world, all came back normal.  Finally a friend suggested I try Zoloft and after a week I felt myself starting to feel normal again and after six months I gave it up, but since then I periodically have PTSD symptoms and 5mg of Valium (don't buy generic diazepam) on those days has been my life saver.  God bless you Pfizer Pharmaceuticals!"
