Presuming you're not using standard street grade stuff, and "alternately sourcing" as i've done a lot with #4 Heroin in the past I've found generally that snorting heroin and drinking tends to lead to a lot of vomiting, or hitting that sweet spot, or just overshooting the sweet spot and having a panic attack whilst I try and wake myself up in between drooling passout moments with random spasms and collapsing into a cold shower. I don't recommend drinking with it, I'd get off the stuff they sell on darkwebs too it's far more potent than what is generally available otherwise, I'm more or less clean now though that was through switching my main source to a street dealer who's gear was weaker and sort of tapering down a bit the last couple of months. You seem to be more or less the same as me Hexagram, about the same age, post-uni and in many ways fucked up. I refused a methadone perscription about a month ago and i'm glad I did, if you've not done enough to get proper withdrawal symptoms yet count yourself lucky I went through £4000 in four months on similar shit thinking for some reason I could get away with it, but you can't and it just makes things worse and alienates you from friends and family more, those that remain anyway.
