What is an alternative to a coffee enema? I'm extremely sensitive to caffeine and when I tried coffee with a colonic, I got really sick the next day (migraine, vomiting, confusion, etc.). I know my liver needs help, but coffee is a BIG NO for me.

No need to do coffee enemas if they don't work for you. You can just do regular enemas without the coffee, or use wheat grass to implant, which is soothing and healing.
