Recently I've been using mdma a lot on the weekends mainly and a small binge during the other week. I was feeling real shitty and depressed lately and I'm not sure if it's because I depleted my serotonin levels? I sometimes expirience afterglows after rolling too which leaves me confused. I want to continue using mdma, but does anyone have advice on maintaining serotonin levels? Is there any vitamins ect. recommended? Thanks.
