I know a lot of pretty responsible users of MDMA (most use during festivals). It’s also best to not do it more than once a month as it’ll significantly decrease the effects.
It’s also important to be mindful that in days following the high may come a low where you feel more depressed than usual. This is due to the low seratonin levels your brain will have after you increased them to levels you’ve likely never reached before.
I also wouldn’t consider MDMA a “trip” per se. At doses like 80-120mg you will be fully mentally able, you’ll just have rose colored glasses on (a fondness for everyone and everything).
Otherwise some other tips are to chew gum as most people have an oral fixation on MDMA and you don’t want to grind your teeth. I hear taking Magnesium before helps as well though I haven’t personally researched that.
