ive done every drug at least once
DXM is the wildest shit, but don't expect to do anything but exist for 8-12 hours if you do ~2000mg. Also DO NOT drink alcohol while on it, not only would you not notice, you'll probably die. Do not take cough syrup for high doses, just get some Sucrets DM. Take 4 to 5 packs depending on dosage req'd and whether they're 18s or 24s or 15mg/20mg each tab. No need to crush them, just heat them slowly in the microwave until they dissolve, strain and put the powder in your drink. Shits are cherry-menthol, so they have an awful taste, but at least you're only getting DM and corn-syrup and not any other pharm. Had homies puke from the taste and sugars, but they still got next-level. Trip is not comparable to acid or mushrooms, it's much more 'real' and you forget you're high, but you won't want to move much, so you're pretty safe. It's not 'trails and patterns', it's straight up animated objects and surroundings being mapped over with sights and textures.
Haven't tried it in ~6 years, it's draining but definitely mind opening. Been an atheist for most of my life, but I still met god the last time.
I have seen pure DM gellies on Amazon, but never tried them because they wouldn't ship to Canada.
