True story, I commented once that coffee made me tired and someone said "Typical ADHD" and it's what lead to be eventually being medically diagnosed.
Goes out partying in the late 90's.
Stimulants were taken.
All my friends were wacked out. I got home and did chores.
So much coffee and cigarettes. My coding time was fueled by them.
I actually have a harder time sleeping without coffee, as the coffee quiets my brain a bit.
Age 43: diagnosed AuDHD.
Psychiatrist: so I'm guessing you have an affinity for stimulants.
Me: Ohhhhhhhh! That explains things.
Now I have a Concerta prescription, and can function like never before.
Counterpoint: being able to drink a cup of coffee then immediately take a nap leads to the most restful 20 minutes of sleep you'll ever have.
Sure I'd rather be affected normally by caffeine, but at least it isn't a total wash.
Literally me.
