Depends. More severe headaches cripple just about everyone equally. But neurotypical individuals have an easier time 'powering through' mild and moderate headaches. If your ADHD is inclined to hyperfocus on the headache though, even a mild one is completely debilitating. Distractability plus a hyperfixation on the distraction is a recipe for a 0 productivity day.

Also drink water. I tend to place my bottle within eye shot of my main focus or i won't drink at all. Dehydration is a big problem.

I literally take my water bottle everywhere. It's improved my life more than almost anything else!
