There is no doubt in my mind that Sensa works. Yesterday I didn't use it all day. I was in Midway Airport and our gate was next to McDonalds. I haven't craved anything in the 2.5 weeks I've been on Sensa. This guy eating a quarter lb'er...I was stalking him. I watched him take every bite. I watched him barely chew everybite. I almost leaned over and bit it myself. Then there was this lady who was eating and ice cream home. I'm positive she thought I was scoping on her by the way I was watching her eat it. Finally I'm like--snap the heck out of it. I got home----starving. And scarfed down 6 cold ribs and about a cup of red beans and rice. Normally that's a ton of food. On Sensa--that's a buffet. So this a.m. I got up and sprinkled a little on my granola bar and I'm just going to watch it. I am never hungry on Sensa.
