I am trying to make sense of a short relationship I just had. Ex raver in his 40s who uses MD every few months or so at EDM gigs but also drinks around a bottle of wine a night plus more. I think he had a coke habit but can't be sure. Constant runny nose, carried mints, mood swings, short of cash at times. Also very slim. His appetite seemed ok but obvs he wasn't up for food after the MD he did at a gig. He denied using regular coke but I'm not so sure. Once I tasted something really bitter when kissing him. I know he offered his ex coke on one occasion. Also that he used in the past. Is it likely he's back on it regularly?
