Not sure if this is what some call “brain fog”. I’m sure I have that regardless due to having high levels of anxiety over my health. However, they’re times where I get this strange “sleepy” sensation that is hard to describe. It kind of freaks me out at times because I know I’m not tired yet I feel like I drop and fall asleep where I’m standing. The sleepiness/tired feeling feels more mental than a physical one, and at some points I find a time in the day to take quick nap but of course can’t fall asleep. DAE experience this by chance?
