I took a couple of 40$ boxes of it for a few weeks and ever since, I've had no problems. Pretty great!

I buy a box every now and then since then just to keep it up. It's like the most expensive probiotic on the shelf, but it works.

Oh yeah, and I also stopped consuming crap that goes in the fridge or freezer ready to eat a long long time ago. I think that might have something to do with it. They found that there's certain harmful bacterial species which proliferate in such environments [1]
