Interesting that Buspar may not be as effective when taken alone. I feel I've had really good results with it. I also saw a counselor that first month, so maybe it just works better combined with any other form of anti-anxiety therapy (SSRIs/ADs or cognitive behavior therapy)?
I was already dealing w/ severe nausea around the time I started Buspar, so if it was a side effect I didn't notice. At least, it didn't make it any worse. The nausea I had been having eventually went away along w/ the anxiety. I asked the pharmacist about this, when I first got the meds, and he recommended taking the Buspar with food or after a meal, so that's what I've been doing. Also, I take 15 mg/day, one tablet I divide in half (I take half of the pill after breakfast and the other half after dinner). Perhaps dosage has an effect on nausea as well? I would also drink ginger tea when I was nauseated and this seemed to help.
