I dont know.
I have thought of the periods where it was under control were the times when there was no significant depression, but in hindsight, there was a significant amount of hypomania going on. Felt rather happy at the time though.

I have been aiming for a depression free mind, and happy to accept the hypomania, even though I have done some stupid, regretable things.

So I am uncertain for how long and on what meds I was ever actually in a relatively controlled and "normal" state.
