The most important thing for hypomania is sleep. So even if you have to take something to help you sleep then do that. Also look at your sleep hygiene. Nothing stimulating an hour before bed. Turn off the tv and put away your phone. Maybe try some meditation right before bed to try and relax. Don’t take your meds until you are in bed and ready to sleep. Try not to overstimulate yourself during the day. Try not to flit between projects and don’t have too many browsers open at once on the computer. Try hard to only do one thing at a time. 
Well that’s all I can think of. Please let me know how you go
