*How bad was your brain fog? I know a lot of people use the term brain fog, but it’s almost hard to believe anyone could improve this aspect having lived it for 6 years with no relief.

I've been doing some testing the last few days with a simple blood glucose meter. I find if I eat carby foods, I get lots of fog and fatigue and it correlates with a higher blood glucose. But if I eat low carb foods, I don't get the fog -- or at least as much.

Ketosis is more for healing and for an added level of clarity. I did it wrong the first time. Not enough vegetables, hadn't been low carb for long, too acidic, etc.

*I’m on day 6 of Keto and currently miserable. I’m supplementing electrolytes and counting macros.

I'd suggest doing a little more research. Take some time to be low carb if you hadn't and be real clean with your diet, and then try again.

*How long did it take to notice difference? I know they say 1-3 months to get fat adapted.

There's fat adapted and being keto adapted. You can be one without the other.
