Juice Cleanse

I'm thinking about starting a 3-days juice cleanse. Living in Hong Kong is not easy at all, it's such a polluted city, and you have to pay constantly attention to your skin and to your body to stay healthy.
And even if you eat a lot of fruit and veggies it's very difficult to feel completely healthy, you always feel full of toxins and just... not good!

I'm already taking milk-thistle pills from 2 weeks (i'm taking them for 60 days).
They are an amazing way to detox your body! But I don't think this is enough, so I really wanna try a juice fast, since everybody think it's SO healthy and you have to do it at least twice a year, it brings you like a million benefits!
Plus, I wanna lose a little weight before going on holiday in 2 weeks :p and I know this is a super fast diet celebrities use to have days before the red carpet. I'm a little bit scared but the -healthy- part really calms me down :D

Anyone ever tried this? Have you got some advice to give me? Something I should know?
