I was misdiagnosed with MDD (major depressive disorder) for 7 years before my BP2 diagnosis so it was a relief to finally be getting the right treatment for my problem, and now I have balanced moods and (apart from being unemployed) I'm pretty happy.
I haven't done anything so manic that would get me sectioned but did have behaviours such as you described that were significantly different than my "normal" personality.

If you are feeling normal and want to try life unmedicated then sure go for it (with appropriate help to come off any meds that you are on) but if when you are off meds you start to get depressed again, or things start to get out of control then please remember your diagnosis and get the appropriate help.
