vicks 44/ the robotussin bottles both have about 640 (maybe 7 or 800) mgs per bottle from what I remember, and you can get two bottles of vicks 44 for under 10 dollars. Zicam is like the most expensive one from what i remember
although maybe theyve changed cough medicine around since the last time I tried this ;/
I would recommend drinking one whole bottle right off the bat and then maybe drinking a fifth of the other one for your first time. but dont plan on walking around anywhere, even though its neat cause you feel like youre walking through the ether.
after i would peak in the middle of the night i would always go pee or something and when i was done i would always look in the mirror and all I would see is the face of an irish farmer with hay for hair and silly teeth
you prolly already know this but make sure you dont eat for a couple hours before hand, or it really fucks up and delays the high, plus it can make you puke! also make sure you only get the ones with dxm in them, but im sure you knew that too.
