first of all, you aren't alone. we all understand to one degree or another how thoroughly interfering brain fog is. Secondly, those things aren't so bad. Once I came home, wanted a nice cup of tea. Filled the tea pot. Hit the switch to the electric tea pot. Went inside to sit and watch tv. Totally forgot about the tea water, never heard the whistle blow. All of the sudden, I smell burning plastic! I ran into the kitchen, see the electric tea kettle sitting on the stove, unplugged, with the burner of the stove on and bunch of plastic from the base of the tea kettle melting through it. Took me 3 days to air out the apt.
Another time, I totally forgot that we aren't allowed to pop popcorn at work (the steam sets off the smoke detectors when the microwave door opens and brings in the fire marshall). I come to work with my nice lunch all packed. Decide around 3 that I want a snack. Throw the popcorn in hit the button, take it out and WHOOP, WHOOOOOP, WHOOOOOOOOOOOOOP! Off goes the fire alarm. The entire building had to be evacuated and the fire marshall had to come. Lucky for me, we weren't fined. Still getting flack for that mistake.
Too many times to count, I have gotten in the car, started driving somewhere I know well how to get to (like home) abd ended up lost or driving past my exit before I realized it. That's mighty embarrassing for me since I am pretty much known for my sense of direction!
So see, your brain fog mistakes aren't so bad. Cherry flavored cauliflower might not taste delish but it sure won't kill you!
