anxiety
"I have recurring bouts with severe anxiety.  Six weeks ago, I was put on 30 mg's of Buspar to be taken in the morning and at night.  I got "brain zaps" (similar to Paxil withdrawal) and nausea lasting about an hour after I took the medication.  True to most other medicines for anxiety, I felt as though overall, my level of anxiety increased over the first 2 weeks although I would have periods where I was not anxious.  After 2 weeks the Dr raised my dose to 60 mg's. I found it best to take 4 times a day because I definitely feel it wear off. While this has taken my overall anxiety from a 9 to a 7, it is still not enough."
