Everyone has different opinions and beliefs.......so here are mine:
Anything that is NOT natural and is synthetic does have side effects.
Alli is just like Xenical (which is prescriptioned).
To make a long story short.......I used to weigh 303lbs and have never had children. I used to be on Xenical and the side effects were just like the bottle says..........very gross. I tried every diet known to mankind.
I decided to eat healthy and excercise and lost 173lbs......and now at about 130lbs.
Personally, I believe this is the latest fad. Once you go off the pill, you will gain the weight back plus more.
I have already seen some nasty effects but I will not share them with you to spare you. Oh, and yes, I am a Registered Nurse
