anxiety
"I have health-related anxiety issues.  Ten years ago I took 25 mg Paxil CR for about a year and it was a life-saver.  No side effect, no withdrawal issues.  A month ago my anxiety returned for a new reason. My doctor started me on 20 mg citalopram. I think I had every side effect possible and made my anxiety worse.  I switched to 12.5 mg Paxil CR and within three days was a new person.  For me, there is no better medicine."
