MDMA gives me the most enjoyable euphoria, and makes me genuinely happy.
A fat shot of coke is easily the most intensely euphoric thing I've ever experienced, but it's almost more intense than it is euphoric. Don't get me wrong, the euphoria is definitely fucking intense, much much more so than MDMA, but overall, I like the "happiness" MDMA delivers (almost akin to that of LSD), how it truly makes you happy, it doesn't just give you this orgasmic feeling of euphoria like IV coke does.
