You're right. You are probably right a lot of the time, but you were wrong this time.
I know of people who aren't even autistic who can't function properly in the mornings without their caffeine fix.
Yeah, Pandora is one. She isn't a morning person at the best of times and stumbles around half-asleep until she has her first coffee of the day. I don't see the harm in having 3 or 4 coffees or teas a day. She says if she has to miss even one day of caffeine, she starts to get horrible headaches and I don't want to see her suffer.
My husband doesn't drink coffee, but he still has to have a caffeine fix in the mornings. He drinks Coke, even for breakfast.
There have been some times he tries to cut it out or at least cut down on the number of Cokes he drinks.
If he stops cold turkey, then he gets migraine type headaches for the first few days.
