I usually feel it the night before it starts, I cant sleep and dont feel the need to sleep either. In my manic episodes I can function on 2-3 hours of sleep. During the episodes I can annoy myself, I talk very quick and do not like to be interrupted not even to tell me to slow down in my mind that means youre not listening to me (during mania). As a child my mother always referred it to being on ZOOM. Im typically extremely happy. The best way for me to put it is I believe I can build a house in a day.
