Be careful of sweating a lot - be aware that you lose potassium (and you already use more potassium when you get the methyl cycle working) so you could wind up with a deficit. I cannot tolerate more than 10 min in a sauna nor can I tolerate SWEATING IN THIS HOT WEATHER!!! (I almost got heat stroke AGAIN). Sweating also drives your blood pressure up if you have blood pressure issues - it drove mine up to 190/90. So...sweating is not good for everyone.
