Most of the times I've done MDMA did not have depression following, and that's a lot. The few times where I might have felt a little down afterwars was easily remedied with 5-HTP.
The comment, "it gets worse with every dose" is complete BS.
It's actually one of the things that I attribute to getting out of my life-long depression, along with other practices.
Saying, that "drugs" are "no different than being drunk" is also a total fallacy. In fact, that indicated that you're lying about your own experience. They aren't all the same, and referring to all illegal substances as "drugs" is something non-users say.
