Coli! I am not dr. Bailey...BUT, I have had worms in my vagina...it is not a fun feeling. It just means the herbs are working. Keep it up you are doing great!
As far as the constipation goes, I wonder if you are doing too much at once....? My thoughts would be to drink lots and lots and lots of water, and stop the DE for now as DE can constipate. I would also stick with the regular schedule as come day 10-14 you may see a big change in how you feel and eliminate, but for sure drink lots and lots and lots of water.
Is this your first cleanse? Are you doing the colon cleanse at the same time? Or just taking Psylium husk as well?
