I would avoid the alcohol in excess. A touch of red wine would probably be fine.

The sex issue is one I'd love to have. Since I got hit in May, libido has went from through the roof to non-existent. I read something about a hockey player being told not to have sex after a concussion, but I'm not sure I've seen anything concrete on it. If you don't get symptoms from it, I'd say go ahead, it can only help.
