I have been pilling every weekend for the last month. always on saturday night, with a proper preload, no food and no alcohol, pot or other drugs, maybe just a little meth-am before the pill kicks in to help it along. I have not felt a reduction in the intensity or duration of my pills yet, Pill's hit me hard, and for a long time. Friends of mine who are approx the same build, but have been pilling longer and more often don't get anywhere near the buz I do. but to prevent my body building a tollerance, I am planning to take a couple of weekends off. My question is: will speed, acid or any other drugs taken in my "off" time, affect my body's ability to tollerate MDMA? That is... I want to have a little meth this weekend, but wont if it will keep my tollerances up. Should I go full clean, no drugs at all? Or is a little speed or acid ok between pills? (a little speed means one or two lines, less than a point)
