"i am taking this medication due to pre diabetes, insulin resistant. i am taking it with metformin. i am up to the 1.2 dose after two weeks and i have lost about 3 lbs, however i feel really sick to my stomach and i have had headaches everyday. i am not hungry and food does not taste the same which could be a good thing. i find it hard to figure out what i want to eat and then i can never finish it because i get full faster. so i can see that this could be a really great way to lose the weight but when i test my sugar it&#039;s still at 160 so i am not sure if it is doing what its supposed to do. i am also having trouble sleeping, not sure if that is a side effect or not."
