C.T.
I have used it and found no side efects except the taste! there is the pill form, liquid form and tea form. The tea was probobly least effective. I didn't notice a huge increse. I had better luck with beer, slightly controversial but for me it was worth it (other countries are big on this meathod) Drink a beer before bed time and in the morning you'll be full as can be. Different beer works better then others. I would not do this everyday, it becomes ineffective if done that frequently. I have heard the oatmeal has a similiar effect.
