When you become manic, is it like flipping a switch? Or is there a build up where it escalates more and more?

Im asking because I was up for 24 hrs recently due to a mistake I made with my meds (accidentally took my adderall at 2am 😳) and since then I’ve been in a fairly upbeat mood which is rare for me lately.

I was diagnosed bipolar 2 early this year so I’m new to being aware of things like mania/hypomania and how they are unique to me, what my warning signs are, etc. 

I’m on Abilify, Wellbutrin, and an antidepressant. Plus adderall for my ADHD. I just started Wellbutrin 2-3 weeks ago so maybe it’s just finally kicking in? Or am I slowly on my way to manic? If it can be a slow build. Because I’m definitely not fully manic/hypomanic atm.
