Big Al, you say you are making mistakes. The first question is, Are you getting enough sleep? Think about it.
=========
I just read a book about the brain, and it said that brain states persist. I find that sleep persists in my brain. That is, after I wake up, I remain foggy for a while. I wait to take a shower (which requires good balance), take medication or drive until I know I am fully awake.

This would apply to cooking, too.
