Heard of these from friends that say its a natural way to help burn fat.  Working super well for them.  My question is, anyone in the wls community ever use them?  I had the RNY in 2003, and have gained back a large portion of my weight.  I will talk with my dr. soon to see what she has to say about it, but just wondering in the meantime...wondering about bowel issues, digestion & absorbtion, etc.  Anyone?  Thanks:-)
