Advice for attending a concert this Friday? Good or Bad Idea?

Going back and forth between taking Molly 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 Molly 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 this present substantial risk? Thanks
