sauerkraut has been very helpful. The water kefir is helpful, but I can't take it every day as it seems to overwhelm my digestion & increase constipation. If I take about 1/2 cup every few days, it seems to be good. I think i have congested gallbladder & liver, so things seem to get backed up if I push too hard. I get headaches, acne, increased constipation etc. So I'm trying to be patient & not push too hard....
