If so, did it increase your sulfur levels even more? I'm having serious trouble with what I think is increasing sulfur levels while taking antimicrobial herbs and antibiotics I've tried for a UTI/bladder infection. I've tried several herbs and 2 different antibiotics (which were not sulfa based). I get extreme head pressure/tension when I take any of these. Molyb and boron seem to help reduce the pressure a little, which is why I suspect sulfur and my test strips show about 1200 despite being on a low sulfur diet for wks. I've talked to several drs. now and am not getting any help. Any insight would be appreciated. I have 2 hetero CBS, SUOX and homozygous for A1298c. My sulfur levels were relatively low before I started taking the meds for my UTI, which still isn't resolved. Thank you.
