@SecondUniverse ADHD, swallows metric tonnes of pills at one go. My wife and stepdaughter are both ND and have difficulty with *one* large pill; they ask me to find Wee Smol pills for them, or gelcaps....

Anecdata not big enough to run stats on, but....

@SecondUniverse
I generally don't have a problem with both, but had as a child.
Especially since back then blood was drawn with a syringe and I still rember getting multiple syringes drawn from one spot and the needle moving around in my arms.

Today it can happen, that I have a reaction, probably falling of blood pressure and not enough blood getting to the brain, but it usually doesn't happen.

@SecondUniverse

I often don’t bother with painkillers because by the time the pain is registering, ordinary painkillers often aren’t up to the task.

I had a lot of trouble swallowing pills & capsules as a child, but gradually overcame it. Very occasionally it troubles me.
