First of all, congrats and welcome to the world of cleansing! I think you'll find as you learn more and more that it is very gratifying to have a direct hand in dealing with your own health. Someone else may want to comment specifically on the effects of Antibiotics with the MC, but I was thinking you may want to do some more reading on the phenomenon of what we call a healing crisis. It is very common for physical ailments to come up when cleansing - cleansing stirs up bad things and then attempts to eliminate them. So usually you feel worse before better. Antibiotics and drugs supress symptoms. So it appears that your bf is doing to things that have the opposite effect. One one hand, if you can handle the healing crisis and suffer through it, that is great b/c afterwards you'll feel much better. On the other hand, if it is too much, you may want to back off and do a more gentle cleanse until you feel up to it. I would like to say ideally he would stop the meds and do the cleanse only, but only he can decide how serious/difficult it is and he should listen to his own body. So in short, do some reading and have him do some reading on healing crisis, then decide what is best. Part of all this stuff is that we do take health into our own hands much moreso than before and there is responsibility with that. Good luck and happy cleansing!
