Does anyone know about this new diet thing? I have been reading up on it. I would like to give it a try. I was scared that it would make a person jittery or give you heart problems like the other stuff that is or has been on the market. Oprah did a show about it and CBS News had a special run on it. It comes from a cactus plant in the African Desert. I was in Rite-Aid Pharmacy last nite and they carry Hoodia products- boy are they expensive.
