I am very happy I found this thread. I'm a 25 year old, healthy male. I noticed for the past few years that tea (especially black sweet teas) have attributed to me vomiting. It started quite a few years back during a hot virginia summer. After running I came into the house and probably chugged about 25 oz of sweet tea. Less than 5 minutes later I was vomiting. I thought it was due to exhaustion and wrote it off. I rarely drink tea but do enjoy it on occasion. A couple of weeks ago I went into work feeling great and ready to make some money (I'm a server). I was just getting over a cold so I decided to make some hot green tea. I drank the whole mug in about 20 minutes. Ten minutes after finishing I noticed I was getting really hot, dizzy and kind of nauseaus. I snuck into the bathroom to text and out of nowhere felt the urge to vomit. No sooner than I entered the stall did I start to vomit horribly barely making the toilet. I don't understand why Tea would do this to me. At this point I thought there was an underlying issue. Today I drank about 8 oz of tea just to check whether or not it was sweet or unsweet and sure enough, 5 minutes later, I was back at the commode vomiting. Has this ever happened to any of you guys and if so, have you any idea what it could be? WHen I drink the fake stuff I am never adversely affected. Only when I drink real brewed iced tea. Looking back, every time I vomit and I'm not drinking alcohol or have the flu, there is always iced tea involved. This is very strange. If anybody could shed some light of this I would be forever indebted to you. Thanks for everything, folks. David D. Richmond, VA
