Allright, I'll clear this up, I get this stuff about 3 times a week out here, Here in NC Cheratussin AC is OTC, all u have to do is find a mom N pops pharmacy and show ID and u can purchase it, the whole bottle has about 230 mg codeine in it, and I usually take half the bottle at a time,, I've never gotten sick or any side effects from it, yes it's a lot of guaifenesen but I've NEVER gotten any side effects, and half the bottle gets me a decent buzz and if I'm in WD it'll keep me well till the next day, so it defintely IS worth it, and I have a moderate opiate tolerance, it u dont know how much to take to equal your hydro dose just google narcotic converter, and one of those will help u out,
good luck!
