Hello, I have stage 4b cervical cancer. I bought some RSO, suppositories and other stuff. I don't know how to dose myself. It's my understanding that I need start with a small amount....then increase. How much should I start with and how often? I've had 3 chemo treatments so far. Now I'm due for a PET scan. I want to get CO in my body ASAP. Can someone please direct me? Thank you.
