I must come off as drunk/high a lot, in lows & highs but in different ways.

When hypomanic I would agree it's mostly just the disinhibition that comes off as drunk I think. Like laughing/giggling inappropriately, saying weird things, yelling, ranting & raving, I've danced around. I do get kind of uncoordinated, drop everything, run into stuff & make careless mistakes mainly due to the fact that I can't maintain focus on any one thing.

When you describe having an empty look in your eyes, swaying & loss of balance I would say I might have those symptoms but more when depressed & dissociated.
