I have been on Fastin for 6 days now. Have not lost 1 lb. as yet. What it has done is stop my cravings for sweets, which is good. The thing I have noticed though is that twice now at night after eating something around 10pm on, I have thrown up. Very strange. Feel sick to my stomach, which is keeping me from eating.

Has anyone had this experience of upset stomach?
