Combinations - amphetamine+mdma

[bongripa]

Swims been playing around with this pretty well much all summer. he finds it to be his personal favorite combo for his areas seemingly endless stream of all night summer parties.
Amphetamine+mdma seems to banish the come down from the mdma. He used to be really retiscent to take mdma often cos of its serotonin depleting qualities & hated the empty feeling when it was wearing off. Candyflipping is an option but too 'relaxing' for a hectic party. Swim expected harsher after-effects of this combo, but they don't seem to be appearing.
Last saturday he took 2 oral doses of around 200mg speed 2h apart (average UK street quality) and a 150mg dose of mdma a bit later. After a very active dancy techno n' psy party he carried on for around 20 hours afterwards, shopping, hunting for another party... Tidied up with a big meal, 5htp & l-tyrosine. Then slept for about 12 hours. The following day got back down to work with no real feeling of badness (far less than if i had been boozing all weekend.)
There must be some badness, what do SWIY reckon? Will his tiny brain fry in its head? What's the best thing to do/eat to limit damage? Swim always eats alot of calories when partying, which helps alot.
He doesn't do anything regularly & keeps substance use only to party nights...
