Has anyone ever did IP diet on their own by gathering the info you need from here and purchasing the products on e bay. I don't know the prices of the products at my local clinic so I wouldn't know if I was getting a deal or paying too much on e bay? I have the Phase 1 instructions and the supplements I suppose to buy and the food list. Im just curious, please let me know because I just didn't want to pay no additional costs at the clinic if I could save money. Thx so much to all!!! Any help, I greatly appreciate.
