I also bought a groupon package for 6 treatments and I've had two. I massaged the heck out of my stomach after each one and drank lots of water and I already exercise hard. After each one I've noticed a huge difference. I've lost so much fat that my skin is actually sagging from the fast loss. I'm not concerned because my skin is still pretty elastic and is tightening on its own. I go for my 3rd treatment today and decided to purchase more to do the back of my thighs. It is actually quite relaxing, like a warm massage on my belly and I fell asleep during the last one. The sound I hear reminds me of crickets.
