only you and your treatment providers know whether you are having a manic phase. everyones manic phase is different example I know when I am in manic phase when my wife tells me I am talking real fast and I find I am making snap decisions rather than thinking the situation out. my wife on the other hand knows when she is in manic phase when she gets the urge to go to the gym every day and is easily irritated.

my suggestion if you think you are in manic phase contact your treatment providers or one in your location, there is some really good meds that can help slow things down for you to an even less manic state of mind.
