Focalin is an isomer of ritalin and supposedly has the same effects, but it's more potent so you need less to get those same effects.
Darvocet is some kind of painkiller, but I couldn't find much other than that.
Has anyone ever experienced either of these drugs? I'm leaning more toward trying the focalin, but I just don't know how much to take and what it'll do. Erowid didn't help me too much.
Please help me out,
