anxiety
"Was diagnosed recently with generalized anxiety disorder. It has manifested itself differently through the years...mostly Irritable Bowel Syndrome. My symptoms now being terrible brain-fog and jitters. Went through numerous blood tests, stress test, etc...and came to this "anxiety"  conclusion. I decided to try Buspar, as my Mom had been on it off and on and had good results. I was worried about weight gain mostly and this one was touted as not having this effect. 

After 2 weeks into the medicine, taking 15mg/day, I feel pretty good!  Starting to feel back to my old self again. The first couple of days were a little weird, felt more anxious than ever but tried to keep busy and it passed. A little trouble sleeping at night but take melatonin to help for now."
