This is by far the worst product I have ever tried. I immediately felt a burning sensation and sick to my stomach as well. I wasn't going to make a big deal I just figured I'd take a loss, but then they issued a 2nd shipment for double the cost of the first was $18.00, the second $37.00. I guess I missed reading the fine print. No money back guarantee once 2nd bottle is shipped, no return label for 2nd bottle either so you incur shipping expenses in order to get a refund. What a great gimmick for women desperate looking for relief. You both should be ashamed of yourselves.
