...totally not what you were expecting! Has anyone tried this? [video=youtube;JtxBkYT6b6w]http://www.youtube.com/watch?v=JtxBkYT6b6w[/video]
Seems like a silly idea to me. You can flush your system out by drinking water and perspiring. This is just giving you a bunch of hickies. Hickies that probably cost $500.
I did this at a spa in Korea. It felt weird, like the jars were grabbing fistful chunks of flesh from my back. I didn't feel any better or worse afterwards. It looked like I was attacked by a giant octopus.
