So, I have tried everything from working out 7 days a week, eating 200-300 calories under 500 and what I burn, and weight watchers, which these drops truely have worked without making me cotton mouth, dizzy, fatigue, or having nausea. Doctors have gone as far to refer me to get my stomache cut down to a little sausage size. My mom got this surgery and did not work she is gainging just after 6 months, plus all the complications. I have stress induced weight gain, no cure yet for weight caused by stress. Tried everything from eating 300 cals a day to 7 day interval workouts, trainers, and weight watchers. I did do a body fat scan and was told when i eat i build muscle, too much. Im over 29.99 % over the average muscle percentage for women my age. So, do know these drops work and i still eat just stops me once my body has what is needed to satisfy hunger. I do not have any down falls, except the drops sometimes make me well extremely tired, but after rest like 2 hours im good. I think this is due to my Lupus and Hypothyroidism (low surgar levels). So, beware Skinny brand is not the same product as these drops. So, make sure if you want results use as they state and buy this particular product.
