SWIM has taken MDMA before and rolled pretty hard on more than one occasion from molly. SWIM has only rolled about 5 times within a year in their life. About a month ago SWIM found someone they trust and bought beans. They only felt the jaw clenching feeling, but no euphoria. We later found out that there was an issue with the binding agent so that would explain that however last night SWIM got 2g of molly. SWIM tasted it before consuming it and said it tasted very bitter and very much like molly. SWIM and their partner both took a little less than a g and poured it into orange juice like they have in the past. This time they only got the jaw clenching and a slight body high, but no euphoria feeling. Took them forever to get to sleep. The person they got it from said they rolled off it the night before with their friend. Assuming they're telling the truth, SWIM is wondering why they can't seem to get that euphoric feeling anymore. SWIM had a bad headache the night before taking the MDMA so s/he took half a bar to get to sleep. I know that can effect it but is half a bar enough to hinder the effects? SWIM's partner didn't take any medication and s/he had the same issue with the roll. The last time SWIM took any other drug was percocets a week ago. A week should be enough time to where it wouldn't hinder the effects right? Has anyone ever taken MDMA that a friend has taken as well where one person rolled but the other didn't? Without any other drugs involved?
