"if you are serious about making a change in you&#039;re life then this pill would be a good starting point. the first week is tough. it made me very nauseous, but if you put up with it, you&#039;re body adapts and you feel a lot better around week 2. it cuts you&#039;re food intake in 1/2. cravings are gone. it also has made me want nothing but water. i usually drink a pepsi in the morning and i no longer have a craving for that. water only. i do get a bit sleepy, i believe that&#039;s from the pill. no headaches. i recommend this pill if you&#039;re serious about wanting to make a change and are not a cry baby."
