I mentioned how coffee doesn't keep me awake, and someone suggested that was an ADHD thing. I had heard people say it's an autistic thing. Which is it? Is it both? Is it just that a lot of autistic people are also ADHD?

@JeremyMallin Could be both (officially diagnosed #ActuallyAustistic here, and I don't seem to be ADHD on top of it). Caffeine doesn't make me "wired" in typical amounts, though I can't rule out caffeine subtly interfering with my ability to sleep.

@hatysa @JeremyMallin I'm both, and I definitely have to stop a few hours before bedtime. On the other hand, I take armodafinil off label for my ADHD, and I often fall back asleep around the time it kicks in.

I'm pretty sure that response to stimulants is particular to ADHD, not autism. But since around 50% of autistic people also meet the criteria for ADHD, it would make sense that people would be confused.
