You won't find it anywhere in the GREATER CHICAGOLAND area except down on the South Side and if you don't LOOK the part, you won't find it. Even though it is OTC it is kept behind the counter, for obvious reasons I guess. I don't care about your motives. Some of these peepz are ignorant and you won't get a straight answer or they just feel like runnin' their mouths when they got nothing to say.
You can find DORMIN or SLEEPINOL on the internets tho' IF you're gonna be cutting dope, and there ARE good reasons to be whackin' your shit, i.e. got 5 g. off of a 10 g. stick of raw, then I can guide you through that shit.
