I've actually been taking the Fill Pill on and off for a few months now and have lost about 15 pounds. I think if I had actually been taking it regularly, I would have lost a lot more. I have taken Xenadrine, and Alli, and had horrid side effects from both. I got extreme anxiety from Xenedrine,and Im not even going to discuss my side effects from Alli, so I was happy to not really have any side effects from The Fill Pill. As far as how it feel, I wouldn't say I feel stuffed after taking it, but I do feel less hungry, if that makes sense. If I take it before I eat dinner, I am not able to eat half of what I used to eat before, and I feel full for a lot longer. I think the fiber in the capsules makes you feel full sooner and longer. I haven't had any real side effects. I got constipated one day because I didn't drink enough water with it, but if I drink at least 2 glasses with it, it actually helps me be more regular and its a lot more effective.
Its a bit pricey, but to be honest, its the only diet pill Ive ever spent money on and felt like it actually helped me lose weight, instead of just caffeinating me. Ill put a link to their website below. If you sign up for their newsletter they send you a $5 coupon code.
