This isn't the 90's anymore, we have dozens of modern studies on MDMA from clinical use and understand the pharmacology better. Druggies are lazy and repeat the sayings from the 60's as if it was gospel even though we know better now.
MDMA is unfortunately not a party drug. Because of the dopaminergic effects you already increase your body temperature, and if you party with it you increase your body temperature even more, and in particular the brain which causes neurohyperthermia which causes what people call MDMA crash, Monday blues, or whatever gay term they invent for it.
Doing MDMA properly means doing it in the way that studies have shown to have NO visible neurotoxicity, no negative comedown, no brain damage, nothing.
Up to 180mg of MDMA.HCl, in a calm and cool environment, without exercising yourself. That's it.
The studies show that a month (four weeks to be precise) between doses is enough for the brain to recover and do it again without causing any damage.
The three months myth was what the woman said during an interview when talking about "how not to lose the magic", which is what happens when you do MDMA improperly (either dose, frequency, or overheating) and cause minor brain damage to your serotoninergic area and can't have the serotonin effects of MDMA anymore.

Here is the source; the interview in which she talks about "no more than four times per year".
