I know I said I was leaving the forum but, I lurk and feel up to replying to this one with a question.

During those periods of intense anxiety, how's your mood? I get periods of intense anxiety where I'm euphoric as hell. Which really shouldn't make sense! Anxiety and panic isn't supposed to feel good. Anxiety causes a ton of people's depression even. Guh. My moods are a mess.

As for the sleep thing, from what I understand especially with hypomania it can be relative to your normal requirement. For example, some people only need about 6 hours per night while others really do need 9 or 10 so, say you're someone who needs 10 and you start sleeping only 5 or 6 and feeling good, that's still 4 to 5 hours less than normal thus, a significant decrease in your need to sleep despite the fact that you're within or close to "normal" range. Make sense?
