I feel like the sensations you describe are about what hypomania feels like as far as euphoria. I personally feel physically driven towards extreme behavior. Like I'll scream if I don't run, drive, drink faster. When I do get going in those things, I feel like I'm literally going to float away which I then find uncontrollably hilarious. I also need to break things/hit things. And my appetite disappears. And sleep starts to feel like torture.
