In my case both meds and therapy have helped. Therapy is expensive and there are not good therapists at my place, but the advice and suggestions I get from PC serve as therapy to me and to this day have helped me a lot.

Meds like lamotrigine(thank God I never had the rashes!), buspirone, amisulphride(very low dose - 50mg) have helped me a lot but then some have made life miserable for me like olanzapine, risperidal, lithium, quetiapine etc etc. SNRIs have sent me down the manic spiral. So its both ways I guess.
