What can I say?? Goolarra said it all................ if it makes you feel bad, don't drink it.
Coffee, tea and coke all come in decaffeinated versions. I used to have issues with caffeine (not thyroid related), so I switched to "half-caff" coffee.
I gave up caffeine years ago when I went hyper. You couldn't pay me money to drink it and make my heart wackier than it normally is. I do miss it though. I loved coffee =(.
but im tiiiirrrred (whiny voice)
Seems like a no-brainer to me. If you feel horrid after drinking it, then DON'T DRINK IT. I've never had a problem with caffeine, hypo-, hyper- or eu-thyroid, but that's me, and this is you. If you reach for it because you're so freakin' tired, but it makes you feel horrid, you'd think you'd stop reaching for it.
