Has this happened to anyone else here? When I first started training quite often I would get nauseous towards the end and 2 or 3 times I even threw up. It was all water/flem and after I threw up I would feel fine. This happened for maybe a month and I thought I was over it- however last night we had a really rough training session and toward the end I was feeling it a little bit (not quite as bad as previously). Anyone else experience this?
