Anyway, taking magnesium definetely reduced my polyuria by at least 80% and reached to 100% by taking S. boulardii and a little bit of vit A.
I have had polyuria at least since 2004 (hadn't slept well for 10 years b/c would have to get up in the middle of the night to urinate and couldn't fall alseep again. After heavily supplementing magnesium for 5-6 weeks (July-August) my daily urination normalized, but every now and then still had to get up in the middle of the night. In september I started taking 10,000 iu of vit A 1x weekly and my last dose was in Nov 3rd when my sleep finally became flawless and urination is not a problem anymore.
My conclusion is that I have been having an underlying calcium problem (even w/ some teeth demineralization), besides de clear magnesium deficiency (aggravated by abx). Supplements that worsen my polyuria were garlic pills eek and taurine.
@MeSci thanks for the links, I will check them out.
