Like FB said, stop working out for 48-72 hours. As you are working out you are burning your fat cells which is releasing more "toxins" . Buy a home test and test yourself after your hiatus from excercise.

Good Luck, for you to work this hard to clean your system and to stick with it shows how serious you are about what you want to do. Alot of people would have given up. This country is lucky to have you.
