Check your blood sugar and blood pressure. That is what got me, for a long time I had a lot of brain fog and just was operating at around 50% which was enough to get me by but once those issues were resolved I feel fine now.

Blood pressure has been tested, and is normal (120/70).

I'd be surprised if I had a blood sugar problem. No family history of Type-1 diabetes. I'm thin/muscular. Workout regularly (lift+run).

I suppose it's possible, but I would be surprised. Human body is a weird thing.
