Pdoc prescribed it at 30mg morning and 30mg at night. It definitely helped. No weight gain which was a huge deal for me. I was also on 200mg zoloft and 600mg lithium. No weight gain from any of them. My side effects were nausea which started with zoloft, continued with buspar and I frequently vomited lithium. Also, memory loss, which I believe is from the zoloft. Buspar helped my anxiety but was also given xanax. I'd give the buspar 4-6wks
