While In Vietnam I took a liquid drink called "Obeasitol"(sp). I lost over 40 lb and maintained my weight of 182 lbs for several years. I lost my focus and am now up to 230 lbs. I have attempted to locate this stuff and no one seems to know of it. I have tried searches for it on the internet with no results. I not be spelling it close enough to be recognized?

Could you help me find this or at least spell it right?
