Skinny Fiber * Any NEGATIVES out there?

Options
I have read for days about the positives of this pill & have yet to come across anything negative.
Anyone have a negative experience? Side effects? etc?

Im seriously considering this product (Just to try, not long term) BUT being the type of person I am, I dont take anything without ALL the facts. I wont even take vitamins cause Im scared of future side effects not discovered yet :/
