My experience with coolsculpting: I had coolscultping on Weds the 27th of april on my belly and lovehandles. This equals 4 zones: left and right lovehandle and left and right side belly. They charged 500$ per zone. Each zone took 1 hour to treat.
When they put the machine (some sort of big vacuum cleaner) on my body it hurted like hell for 5-10 minutes. Knowing that it only lasts for a short while is good. The rest of the time (50min) were painless. I slept most of the time. 5 Minutes after they took "the thing" of my body I got an excrutiating pain in the treated area, I thought I was going to faint. This pain lasted for 5-8 minutes and after that I was good to go. :-)
After the treatment my belly was completely swollen, so I looked even fatter then before and this lastest for about 7-8 days. I was and still am unable to wear jeans and only wear dresses. I also have a tingling, numb, uncomfortable feeling, very annoying the first week but a lot better now. And it is just mostly uncomfortable, I never needed any painkillers. One more week and I'm probably back to wearing skinny jeans. When I touch my belly or bump into something it hurts. It takes a couple of months to see the results so, so far I can't tell if it was worth doing it. Since I'm wearing dresses every day I get a lot of compliments on my looks though :-)
JUST DON'T THINK THIS IS GOING TO BE COMPLETELY PAINLESS. FAT CELLS ARE A PART OF YOUR BODY AND REMOVING BODY PARTS ALWAYS HURTS!! :-)
