I have my tummy done yesterday. I almost canceled because of the reviews on here. I had no problem, fell asleep and had no pain taking the device off. I am slightly swollen and a bit numb. Because of the reviews, I took a compression garment with me and have had no problems. Every once in a while I feel a little sting but nothing that would keep me from work. I walked on the treadmill lastnight and slept fine. Hopefully it stays this way and all goes well for the next week or so.
