Hi all. Have read alot on Kefir lately as i have been drinking Yakult (fermented bact drink) and it has been helping. So after much research on Kefir - which seems it should be wonderful with so many strains of good bacteria etc, decided to give it a go - ESPECIALLY since my GUT is my main cause of CFS/FM. SO. I've been brewing it - water kefir and milk kefir - but since im milk intolerant (very) ive only been having tiny bits of it. I can drink the water one down ok - tastes fine actually. However the last few days ive had like 2 cups of the water kefir, and ive had alot of nausea and quite bad headaches. Also the main thing.. Im getting symptoms of YEAST brain fog. Im very intolerant to yeast (in breads / drinks, whatever) but i thought because the yeasts in kefir are supposed to be "good" yeasts.. they mite not affect.. but it seems im getting yeast symptoms from it. Not sure if thats just an initial thing because the gut flora is changing around and body is reacting to such.. or if it's just that i cant tolerate any yeast even good. Anyone else had experience with it? Thanks.
