I think your doc will probably only add another 10mg. Either that or another drug to combine with Prozac but it seems to make more sense to just up the Prozac a bit since you're doing better on it. Good luck, hope it helps. Till then, perhaps you could schedule to do something fun and relaxing at the time the "low" starts to kick in to avoid feeling too bad? Walk time with my dog is a picker upper for me. Hugs, let us know how it goes
