After effects

Last night my partner and I had a pretty rough 3 hour session. When it ended I was sore, covered head to toe in sweat, and I was shaking, so all was great lol. I went to get up and damn near fell over because I was light headed, my depth perception was off, and my body just felt weird. Like I was operating it but it wasn't mine. Today I still have a really light and floaty feeling in my head that hurts just a bit and my legs feel half numb and I get an odd sensation when I move them. We've never had a session like that before so I dont know if this is normal or not and I dont know what to do about it.
