I'm like you, I need my sleep. So while I do feel a decreased need for sleep in hypomanias, it's not like I only need two or three hours. It means maybe I get six and feel fine. But just like you, if I do that for a couple of days it catches up with me and I crash sleep wise the next night. But in my mind it still counts as hypomania because of all the other symptoms I get. Everyone is different. Just because you don't have the classic hypomania symptom of needing less spell doesn't mean it's not hypomania. Everything else you said sounds like hypomania to me. However I'm not a doctor so take what I say with a grain of salt.
