Curbing a hypomanic episode?

I have been hypomanic for about a month now, but I only became aware of it fully a couple of weeks ago (the symptoms got stronger). Prior to noticing I just became aware my sleep was less but the euphoria, agitation, spending, etc kicked in in the last 2 weeks. My psychiatrist is aware and following me closely. I just don't want it to get bad and ruin my life.

I took most of the week off of work luckily. Any tips to bring myself down and avoid a depressive crash if possible? My doc told me no weed/alcohol (I slipped and took a hit this evening... but its Friday night and all I wanna do is party and have fun). I've been avoiding stimulating people as much as possible, not too many social plans, resting as much as I can. Will weed completely derail me? That is one of my biggest struggles avoiding. Thank you!
