MDMA this Friday

Going back and forth between taking MDMA this Friday at a concert with some friends. I had my procedure done this Monday April 14. So by Friday night will be around 4.5 days. The advice from the clinic was not to work out or get heart rate above 100 for the first 3 days. I don't smoke or drink alcohol or caffeine, so I am really just curious if these recommendations are more to help the recovery by preventing chronic use. I would just be on the MDMA for around 4-6 hours and then would be eating healthy and taking care of my hair. From the research I have done, it really seems that as long as I do not dislodge grafts I should be fine, does taking MDMA present substantial risk? Thanks
