help me clear things up about the hcg diet?

I have been looking into this hcg diet….. thinking about giving it a shot.
but i have no idea where to start! this is what i know….
no make up/soap/lotion, 500 cal + oral drops, scale for food….

so i guess my question would be… can someone give me a breif overview?
also im huge on make up…. base and eyeliner mostly. makeup chooses? soaps?
i would like to buy the oral drops off ebay… it saved my sister money. what else would i need from there?

also… im about 155, 5′1….. goal weight would be losing about 25-35 lbs. how long should i do the process?

Thanks

and please…. i ask that i dont get any “no sugar and lot of exercise” spills.
im an adult and would like to make my own choices….
