But I wouldn't lose sleep over it.

I get headaches that last forever when I drink a lot of coffee. Strangely, I don't have any consequences from tea.

I understand that. I have a limit in how many cups (what's metric for cups?) a day I can have (three) past which I usually get the worst headache. That wont happen with tea (usually because I wont drink tea.)

There are other things going on in coffee besides caffeine...

I drink tea by the gallon. Well, maybe one gallon a day.

Yes, there must be other things going on in coffee besides ...

Hmm, me too. If I have more than two cups of coffee, I am susceptible to a migraine.

I usually drink decaf tea at home, though, so I can't compare.
