Okay as title states. i have in the pas tried numerous psychedelics but never dossociatives like dxm. So tomorrow i want to try it. I can dose up to 300mg max dose once off. As its dosed @ 15ml/5ml and its a 200ml container. So tomorrow is my mates bday i we decided to try this. i wont do any other meds from now on except for weed. But this is for only tomorrow. But for me i want to start of with 150mg once off and gauge it from there or will that dose be to low for first time with previous psychedelic exp.
