I have no idea why it fixed it but it did. Not overweight, so that wasn't it. I heard that keto can do it, so I thought that this is a better option than surgery or a cpap machine. In this n=1 study it totally worked. It wasn't exercise ether as I've only been doing that on a regular basis for the last 1.5 years.

Eat leafy greens (veggies can be a ketoers best friend)
