Pretty much the title. I've been training for 5 months, injured for 4 weeks in there - just came off of a 2wk recovery from a knee injury. I'm relatively young, 6ft 175lbs, in pretty decent shape.

But I overexert myself to the point of vomiting nearly every class. It's frustrating and embarassing.

I've started doing more cardio and have improved a lot in that regard, but it doesn't seem to help at all on the mats. Do I just need to do more cardio? Is there something nutrition-wise that could help? Open to any and all suggestions.

Edit: Thanks everyone for the advice. I will try 1) not try so hard and ask partners to help me with that, 2) advice to talk to my doctor - I have in the past and he wasn't much help - but it got me to do some research... some medication I'm on can cause hyponatremia, which can cause nausea and vomiting especially after exercise... so I'm going to try a saline solution before/during class and may report back if it works.

Edit 2: took a 3% hypertonic salt solution to class today and it seems to have worked. I asked a higher belt to really push me in a difficult roll after class to test it. Not certain yet, but seems to have fixed the vomiting

Hey, your comment got me to do some research - I found that some medicine I've been taking actually can cause hyponatremia and some symptoms I've had during other exercise are indicative of hyponatremia (severe cramping in addition to nausea/vomiting)... so if I've been sweating out a bunch of salt and am on meds that cause hyponatremia, it could actually explain some of this. Thank you, I'm going to try to drink a salt solution before and during class and will report back if it's a miracle cure or if I'm just a spaz.

Edit: the salt seems to have done the trick. Going to have to test it again to be sure.
