I think most of the time that I was rolling I was taking way too much...
I am extremely sensitive to MDMA, MDA, and even MDE. Pills that are considered MDXX low act like MDXX high in me. Rolling for me was a crazy intense experience. The first time I rolled, nobody had ever seen anybody roll so hard. I was around a bunch of veterans at a house party and they were seriously freaked at how messed up I was. The pills we got were caffeine/MDA/meth combo pills - these exact ones (my buddy sent this in)

It was as if my very soul was on fire. It started off rather poorly too. I wasn't feeling much of anything even an hour after my first pill which is why I took the second one. I still wasn't feeling anything a half hour later but we went out to watch my friend spin fire and hit me like a train. I ended up in the back with my roll buddy all night, pretty much completely unable to function.
I only ever met one other person who rolled as hard as me. It was so funny when her boyfriend came to get me at the outdoor we were at because he thought she was ODing and I looked at her, moaning and babbling and spazzing all over the tent, and was like "Jon, dude, she's just rolling hard. Wait til you see me when the sun goes down tonight and you'll see what I mean" - he found out later haha.
Believe it or not, I've actually rolled harder than that even. And still with doses most would call "sensible" no less.
Considering that I have a stubborn tolerance to pretty much everything else, including other phens, my lack of tolerance to MDXX is remarkable to say the least. Even in my heavy abuse days, I never gained a tolerance that put me much higher than what normal people would take. As long as I had the serotonin to burn, I was good.
Looking back on it, I wish even more that I hadn't gone so crazy with it because it really was quite the magical experience. I guess looking at how high it got me, the intense comedowns that I had make a lot more sense in retrospect. One would reasonably expect to have some sort of panic disorder emerge when you're going that hard, especially since I was doing it every weekend for quite awhile... I had forgotten about most of this until this thread started me thinking. I've had some pretty insane times on MDXX. I don't give the class of drugs the credit that it deserves because I would do so much that I'd fry my brain and forget about everything. I've got chills just reliving some of these memories though. Wow.
