.I'm not surprised, your body is probably in full on damage control mode. If you take care of yourself you should eventually heal though. Drink at least 3, preferably 4-5 liters of water a day, eats as many fruits, veggies, and superfoods as you can while avoiding processed, frozen, and "empty" foods, exercise as much as possible, get 8+ hours of sleep a night, and be outside as much as you can. Meditation and yoga will also help.
I have been eating bigger meals and drinking more liquids recently and have gained some weight. I get high everyday on weed and usually dxm and mdma 2-3 times a week. I've never been in a "rolling crowd" or been to a festival or anything that mdma is frequanlty used at here down in the good ole south ecstasy is semi rare and I'm the only one in my friend group who uses it regularly. So I was trying to get a little bit more knowledge of mdma.
