Hey,
I was wondering about this a while ago because I was showing a lot of the symptoms of hypomania (feeling wired, giddy etc.) and I was highly energetic, but I still felt physically tired sometimes during the day and was yawning a bit.
I just didn't want to sleep at night because I was so hyped and had a thousand more interesting things to do than sleep. When I finally forced myself into bed it took me forever to go to sleep, but I still slept 6-7 hours.

So do you not feel tired at all during your (hypo)/manic episodes? Or does anyone relate to this? Is it still a hypomanic episode if I get bouts of tiredness and yawning during the day??
