Ecstasy: Hit or Miss

[Gozaggss]

the first couple times SWIM rolled, they were fantastic. the first 2 times were both in england, and were at raves. he rolled again when he got home later in the year, it was amazing one day, then so-so the next. and since then, rolling has lost it's amazing methy-speed thrill. months separate all these events except earlier this year which was 2 nights in a row and the 2 england ones were about 4 days apart. could the differences just be from the pill, the enviorment, or possibly a tolerance gained from taking other stimulants like methylphenidate (ritalin) on a near daily basis. (does methylphenidate weaken a roll?) a little englightenment would be great, thanks.
