It's hard for me to say how long they last. I can shift pretty fast, within hours. I think I'm always cycling. I don't think I ever stop. I think I used to stop, when I was younger. I mostly had depresion. But now I think I'm mostly a combo of mixed and cycling so rapidly I can't tell where the tail ends and the head begins, if you see what I mean.

I think I have maybe one day breaks occasionally.....

but, I think I'm less manic manic and more hypo most of the time. I would say I probably have more of a mania swing two or three times a month and then a constant low laying depression under it....
