Too much tea? :(

It is possible that the salad or fruit was contaminated with listeria or e. coli. I’ve had listeria, not fun (lived in the bathroom for a couple days).

Maybe if you had too much uncaffeinated tea you could get over hydrated, but caffeine is a natural diuretic, which means it makes you pee more.

Some teas that are marketed as detox teas contain natural laxatives, which can make you feel sick if your body reacts more strongly than you expect.

The only other thing I can think of is if you had kombucha and the scoby was bad.
