I have been too a couple of 2 hour mma sessions and each time i have struggled to get through them as i get light headed but more nauseous than the light headed symptom. My aim was to increase my sessions going forward but is this my body telling me its too much and i should just do an hour each session when i go. i mean the end goal was to get into competing but im now thinking my body wont deal with it. I have the sick feeling for about an hour sometimes more after i finish my sessions too. What are your thoughts on this?
