Apple cider from the grocery store. It's been pasteurized.
Classic Coke. Keep it outside your fridge and shake it up to get the fizz out before you add it to the drink.
I'd advise you to get 4 of the Ultraphos at a time because of needing to do more liver flushes in a week or month than you anticipate right now. One bottle will do about 3-4 liver flushes. Also because of the shipping charges.
Also, DON'T run out of dewormers. Be consistent with them. No time out until the main infestation of bugs is gone.
