The instructions have me taking some laxatives and mixing a 238g bottle of powder with 64 ounces of gataorade. Looks like I can have coffee, tea, soda (Which I don't really drink), popsicles... just as long as nothing is red.
I'm not worried about the laxative piece of it, we have bidets in the house and I have an area of privacy in my basement office so can do what's needed without bothering anybody. I say that now, ha ha.
It's the fasting that I won't like.
But it's important to do.
