Mixing X and booze tends to diminish the X high, mixing speed and ritalin is pointless and rough on the heart. Stick to either X and a little speed or speed and booze: personally, I do find Ritalin recreational, but it's still best saved for work situations, getting through tasks you really hate - it can even make them fun. But all the posters above are right - mixing stimulants isa pretty much a waste of time. A little speed goes well with X - but too much and it'll overpower the subtler effects of the ecstasy. If you have good X, then why taint such an elegant high with the vulgarities of speed and booze?
Oh, and JKTM, we gotta stop meeting like this, but I'm with you: it ruined my little MDXX clique when everyone else started getting heavily into coke. Blunts the delicate rush with crude dopamine surges and leads to a, as we say in the UK 'fucked', rather than 'high' state: you get more wasted, but so do the drugs, losing the most enjoyable aspects of both. Of course, now that most UK 'coke' contains virtually no cocaine per se (much of it's ethylphenidate and MPA cut with synthocaine, that kind of crap), and MDMA's made a bit of a comeback, people are a little more selective. Sadly, a lot of them select the 'coke', out of habit, even when it's downright dysphoric. I've done the odd line or dab out of curiosity, over the past two years, being mostly a downers and opiates man, now, and I swear, most of them haven't contained any coke at all, just a mix of random stim and random aneasthetic, sometimes in the form of a lame coke analogue.
