Mine tend to include many to all of the usual criteria. It might be more on the elated side, or more on the irritable end. Or, fluctuate throughout the day, depending on how it is triggered. Lower mania (hypomania) for me usually includes:

• Talking a lot, often fast, and usually loudly. Perhaps some aggression in my voice or flat out over the top enthusiasm/joy. If writing, writing A LOT.
• Being so enthusiastic about my own thoughts/conversation, that I barely pay attention to others'. I might talk over them. My yapping usually changes direction (topics) quickly. I often get what I call "Star of the Show Syndrome" and maybe get a little to into storytelling or trying to teach people things.
• Higher physical energy and endurance. My thoughts go faster than usual and like above, jump from one thing to another.
• I am more impulsive and disinhibited than usual. I might say or do things I would normally not. If just hypo, they may be a bit over the top, but not scarily so. In any case, people DO notice, though strangers may not realize it's an illness. They may see it as personality oddity or emotional change. Judgement and negative responses from others are frequent. I can get in some trouble.
• I can't sleep (or not much), but particularly because I don't want to.
• Many things start to seem brighter, more interesting, more exciting (or so to the opposite end that I have anger outbursts or anxiety freak outs). I feel more "in the groove" and "at one with God".
• Psychomotor agitation (moving around fast, can't sit still, fidgety). Fast, fast, fast. No patience. My heart beats fast, I might breathe fast.
• Grandiosity (I feel like what I'm doing I'm doing GREAT. That everyone else is less intelligent, creative, hot, than I am. That my potential has increased, greatly.)
• Hypersexuality, sometimes.
• Feel even less pain than usual. [I have a history of accidentally injuring myself because of being a little reckless, not paying attention, anger outburst. Yet I don't feel the pain that much.]

Sometimes I'm oblivious to being in hypomania, especially in the beginning. I might rely on someone (usually Hubby or a pdoc/tdoc) to tell me I'm hypomanic. Or, if it goes on a while or gets worse, I might find insight. Or not. Before my diagnosis, I had virtually zero insight.

Full blown mania, on the other hand, includes all of the above but exponentially worse. It can elicit fear and become very dysfunctional.
