I have been hypomanic since Sunday. Racing thoughts and speech, running from activity to activity, bored if still and very social. Plus very agitated and irritable with euphoria. After not sleeping well at all for the last four days I decided last night to take 5mg of Zyprexa and finally got a good sleep and today feel calmer and less hypo. Clonazepam wasn't working for me very well. I hate Zyprexa and haven't taken it for months but as a one off to stop hypomania it works well. Getting good sleep can be a key to easing the hypomania. Take whatever helps with that. The laying in a dark room idea is great too. I find it helps but it is very difficult to do cause you want to get up and do stuff rather than lay down. Good luck. I hope you calm down soon.
