dude, stop for a really long time. and i mean a REALLY long time, just stop. don't do it anymore. find something else for a while. mushrooms, mescaline, you can get 24 whip-its tanks for 20 bucks at a head shop, you'd probably really like that.
treat DXM like a rare opportunity. make it like a really big reward. dammit, space out each trip by like a month! try a ton of different drugs! just stop murdering yourself, your brain fucking hates you right now and i bet you can't even tell at all because DXM is good at hiding that. i was in your boat, i didn't evne do it every day, it was like every week, but i fucked up and did it two days after rolling and i almost died from serotonin syndrome, i couldn't speak properly and i felt like the slowest person ever.
