My DOC is IV Meth, once or twice A week, .35-45g. Leaves me thoughly thwhacked for about 14 hours. Twice now, i have followed it with iv heroin....scary...emesis a few hours later...just did not mix well.
I used to use and manufacture meth for years. I've only snorted heroin once but I can't imagine mixing the two. And I can't speak to IV administration. All the best and good, safe times to you, my friend.
Opiates and amps are just not that good of a mix. Benzos synergize much better with speed. Try dope (h) alone if you want the full experience, though I recommend you don't because it only tends to make problems worse.
And ptsd fueled lonesome addiction is definitely something I can empathize with. Shit gets rough. All the best and hang in there!
Be glad it wasn't fr you, as opiate addiction is a terrible beast.
This isn't really a trip report so I'm closing it... PM me if you would prefer I move it somewhere else. I'd suggest Other Drugs, you could just repost there if you want.
