I'm trying to clean the intestines out well before I get to start my next round of Humaworm. When taking psyllium, how long before and after should I wait for taking food or other supplements? I've been doing iodine supplementation along with its companion nutrients. This is such a challenge, since some supplements shouldn't be taken together, or must be taken with food, or taken X minutes or hours away from food, so spacing things further out for the psyllium is going to be tricky.
