Xanax does nothing for me and I cannot stand the taste. I know a lot of people swear by it but it never has had any effect on me one way or another. I started off with Vics a while ago and then the evolution to Oxy then to dope occured. I see a lot of you guys swap between subs and dope, is that a tolerance thing or strictly for drug testing purposes? Cause I normally switch between Oxy and dope for tolerance and cost issues, but I dont have to take drug tests either.
