Herbal Life??

[chager]

A customer of mine brought in some of his Herbal Life (I think that is what it is called) stuff that he takes. He knows I have been having terrible trouble with feeling tired and sluggish. He brought me some capsules that he said to take 3 x a day (I think) There are 6 capsules and he said 2 at time so I guess 3x makes sense. He also brought me a energy bar to try. I am interested in it only because I already eat slimfast bars for snacks and am curious to compare the two. He said the pills are shapeworks total control. This is someone a really trust so I am not concerned about him trying to intentionally hurt me. I am concerned about exactly how the ingrediants in the pills may react to other meds I take. I know this person takes meds for various things though too so I really don't know how concerned I should be. Does anyone take these and how do they affect you?
Thanks!
