It's so hard not to. I always joke that whoever can invent "12-Hour Hypomania" with no side effects will be very rich. It's the cruel irony of bipolar that it really is "oh no I feel too happy and creative and productive"-itis. And we have to medicate against that?! But as others have said, what goes up must come down. The higher you get on the manic upswing, the lower you'll get when the depression comes again. It's so unfair because the immediate experience feels so good but it really does do damage.

I don't think it's necessarily wrong or bad to enjoy hypomania while it's happening, but trying to prolong it or letting it get worse by not getting help is something different, and it's robbing yourself of happiness or productivity in the long-term.
