yeah if ur planning on going out and getting some dxm or emptying ur medicine cabinet of the cough meds make sure ur research it and all the other active ingredients that are in the meds you take, tussin gels work good but its only 300mg which will be prty good for a 1st trip but when i used to use them i would have to take 20 of them and chug robotussin max str. cough (has around 360mg in the entire thing i think) but i also had a tolerance so i wudnt start with that if i were u id start with 20 gels but its up to u
