If you’re lucky, brain fog will attack when you’re blocking someone from the coffee machine. They will startle you when they ask you to move aside and apologize for frightening you.
Don’t come clean. Smile graciously and make a joke about the funny weather you’ve been having.

Don’t talk too much

Brain fog happens to everyone to different degrees.
Don’t be angry. Your tantrums won’t change anything. Accept it and learn how to deal with it.

It will happen

Caffeine can help, but more is not better. When you’ve overdosed on caffeine, the thoughts start to flit unpredictably below the fog so you can’t tell which is the one you need or how to retrieve it.

Don't over caffeinate yourself

If brain fog attacks on a date or at work, don’t sweat it! Make sure they don’t catch that moment your eyes start to glaze over. Take a sip of coffee, make a joke. Remember your cues: maintain eye contact, nod at regular intervals and keep a neutral facial expression. Worst case scenario, they’ll think you’re conceited.

Be poised. Distract or redirect

Over time, you will conquer even your most challenging mental difficulties. Your thoughts may not be linear, but they can be rearranged to create coherence and communicate with others. Your mind may not always be clear, but you’ll develop strategies to use at a moment’s notice.

Go with it

Brain fog is an interesting dilemma. It's hard to explain to someone who doesn't know better, but sufferers recognize the symptoms. We sympathize with each other and accept it is. Imagine a mountain range, with each mountain representing a task that you need to perform.
