Hi everyone. I was wondering if anyone had ever heard of tea causing nausea and vomiting. I am not a coffee drinker, but if I drink tea on an empty stomach in the morning, it causes severe N/V. I'm pretty much OK if I drink it later in the day and if I have had a snack. Even if I don't vomit, the nausea lasts a few hours. Just wondering if anyone else has come across this.
