I'm a creative. In the past I've used my creative side as a means to make a living. I would say that if your meds have you feeling stable then you should stick with them. I do struggle with constantly feeling like I've had my creativity or inspiration sucked out of me - this mostly happens when I'm at my most stable. When I am manic or hypo manic I have more ideas than I know what to do with and all the answers to the universe.

More to the point: I think what you are feeling is normal for any creative. Insofar as I have researched myself, it isn't easy to be creative and produce work constantly. If it was, then everyone would self publish amazing books - so on and so forth. Those who are really driven by their work force themselves to write everyday. It's not always a love fest.

I have had to learn, and in many ways am still learning, how to build up focus within myself to sit and type everyday or pick up a guitar again. Anyways, just my thoughts.
