This happens to me as well in the evening. Days turns into night and I am agitated and want to get out of the house and DO something. I usually have like a strong NEED to get out into a social environment and probably have like five drinks. I'm not manic right now (I don't think) but this is just a part of every day life. Sometimes I stuff it down and stay at home smoking tons of cigarettes or drinking, but some days I simply HAVE to leave or I feel like I will really lose it. My mind gets too busy and I need a distraction. Yes, the rumination. Getting totally lost in thought and dwelling on past events and also obsessing a fair amount. In fact I'm kind of in this state of mind right now. I'm planning a night out dancing for my fiance and I.
