Lots of newbie questions!

Hello, i want to cure my Acne and i have decided to do a liver flush.

1. I was reading the Liver Flush and it said to do a parasite killing program - i have done a bit of research and read that you don't have to? should i do it or not?

2. same with the kidney and bowel cleanse?

2. I am situated in the UK and i would like to know any websites or places to get the supplements.

3. Can you drink alcohol while you are doing the parasite killing proceedure?

4. I am 19 do you recommend me doing it? are there any clear signs that i might not need/or do need to do the liver cleansing?

5. Last but not least, does it hurt? i have been reading alot of posts where it hurts and people have to do another flush in about 1 or 2 days apart.

6. Will i notice changes immediately? and do i have to flush out 2000 stones? will one flush be enough (even if its about 200 stones in the first flush?

7.Any deaths in liver flushing??? (i'm just paranoid)

Thanks for your answers it is greatly appreciated!
