I have tried way too many things including costly prescription alternatives for weight loss, particularly appetite suppression. I bought this without understanding the ingredients etc. and I can definitely tell the difference with appetite control, less cravings, and a decrease desire to snack and eat junk...I am now in the 4th week...and started to notice the change around week 3. Definitely noticed a difference. I typically dont write reviews unless something is totally useless or really good. This actually works for appetite suppression!
