I took the SAME stuff for Acne and ruined my life man. Doxy and other antibacterials wipe the bacteria out of the gut lowering the guts immune systems. U caught a pathogen and your gut bacteria immunity was tied up Witg the antibacterial medications.
The diarrhea was a immune response to try to flush the pathogen out as soon as it landed in the GI Tract. We all get that when we r newly infected. Once the pathogen clings to the intestines it causes disturbance in the colon causing constipation. I would get the biohealth 401h and metamtexteix 2105 combined to save yourself from wasting time tryin to figure out the issue .
I USED to be a bodybuilder.... I went from 215 to 160 now. So don't wait...
