I rolled (one ecstasy tablet) mid-January and I'll be doing it again a month after (i know it's not an ideal gap but i'm doing it anyway) how can i be sure that it'll be effective? Because I've rolled twice with a small gap before and noticed my second roll to be less and even not work at all. Anything i can do to make sure my tolerance or serotonin levels are okay? What have you done in this situation? Thanks.
