But it still beats the depression :)
Yes, there is increased productivity, but the cost is a lot higher than you expect. The messed up thing is you crave it when you lose it - because the certainty is really super addictive.
What I think you're actually referring to is not mania or hypomania - it's called hyperthymia.

It's similar in some ways to hypomania, but different in others.
For one last point of reference, here's a hypomanic episode for me:
Everything in the world is great. Everything in the world is really great. Productivity for a day or two Holy shit, I'm so smart, everyone else is less smart than me! Productivity that is more random Oh my god, I can't believe how smart I am and how pathetic the rest of these people are. Productivity is super random, starting to be unproductive The most logical conclusion is that I'm probably god, like, I really do believe that, that seems very logical right now. Productivity goes away.
I have an appendix that flares up every few years and I leave it alone. I have a pain threshold that I have set that if I exceed I will go to the hospital, but if it stays below this level then I just watch and wait. I have no desire to be cut open unless I need to be. So far this has worked out well :)
The most important thing is keeping you healthy and okay. If you're healthy and okay, then that's wonderful.
One thing I will note, over time, monitor if it gets worse, and be vigilant as hell - it can develop depending on your age and over time, so just watch out. I'd even go so far as to ask someone, preferably someone in your family you don't see more than once or twice a year, to say if they notice a behavioral change in you, just as a backstop in case.
For reference, what finally got me to get help was very serious thoughts of suicide and a hypomanic episode where I quite literally thought I was god.
