I find that my pdoc can often spot mild depressions or the beginnings of manias alot better than I can. He doesn't do therapy but asks enough q to get an idea of where I'm at. Also we have tried alot of meds and I see him often (at least every 4 weeks) when I am changing meds or when things are not good. When things are good I will go up to 3 months or so without a visit.
