Thanks for replying. I’m a truck driver and i thought it was my toilet, but if I’m on the road and I use bathroom somewhere else I’m still seeing the foam. That’s why I’m concerned.. I’ve seen a lot of carnivore videos that healed kidneys. I’m willing to try it not only that I have no problem. I’m already thin, my fear is losing more weight and can’t lose any more weight. I love my wife but she thinks I’m putting too much thought into it but I told her, I’m always tired and sleepy. That’s not normal.
