For me I think I am bi polar II. This is because-
1.) Everytime I come out of a depression even though I have been on the same meds for months I get hypomanic for awhile. It goes away after a week or two.

2.) Even after I have not been depressed for a long time and on the same meds for months I sometimes get hypomanic. It goes away after a week or two.

3.) Recently I started taking Fetzima and for a month I was wired/hypomanic. There is a difference between hypomanic and wired but I was having both.

According to the DSM5 (Diagnostic Statistical Manual) I would be bi polar II.

I don't think having one hypomanic episode caused by starting Prozac would make you bi polar II. Although the DSM5 does say if it comes with the right symptoms you would be.

If I were you I would keep a mood log and everyday write down what you mood is, your symptoms like sleep, appetite, talk a lot, talk louder, overly confident, agitated, nervous, irritable, depressed. There is such a thing as mixed states where you bounce all over the place. Like me, I would be totally hypomanic one day and totally calm the next.

If it goes away soon I would not worry about it and I wouldn't even tell my doc because you really don't want them to tag you with bi polar II. If it continues or gets worse or if in the future you have them again then I would tell your pdoc and they would probably want to give you a mood stabilizer. Keeping a mood log is very important because a week from now you won't remember.

Ideally you want it to balance out and go away and for the Prozac to keep you from being depressed.
