Thank you very much for your response. In '99 I went into the only full blown mania I ever had. I remember this well. I was detoxing from Paxil and was manic the last week of Aug' until first week of Dec' '99. Then I crashed heavily for next 4, lots of sleeping! I get anxious or hyper easily and whenever for whatever reasons. Again, thank you.
Bipolar type 1 features full-blown mania whereas bipolar type 2 features more depression with hypomania. At least, this is how it was explained to me when my diagnosis was changed a few years ago.
