i love DXM. i only do it occasionally as i prefere 900mg (60 pills of generic Robotussin Gel caps, they're new). 900mg is draining, but amazing. if eat the gel caps u should, nasty as it sounds, bite each and everyone. i eat them in rounds of ten, ten every ten minutes, followed by some water to wash the taste out. if u dont bite them there is the chacne u wont digest it evenly. i once ate 40 and didnt bite a single pill. the next day i suddenly felt the DXM kicking in, was not a pretty sight. if u follow my method it should kick in after about thirty minutes following the consumption of all pills (granted: if u eat 10 every ten minutes, u should be done in one 1, and then in half an hour peaking, the true peak wont come for another hour though). DXM is fairly prediciable in that you can assume that if u eat the pills at say 9 30 pm, you'll be peeking at 12, and will be down by around 4 am, the rest is all come down, but be careful the come down can take longer than u think.
