Hello - I used to drink a lot of tea, for many years. About a year ago, when I would drink tea I started getting pains in my stomach, unless I either brewed the tea very very weak or drank the tea after a heavy meal. It feels like the tea is burning away at my stomach. Oddly, coffee does not have this effect, so I've switched to that drink. But, I'm sick of coffee, like tea much better. Anyone have any ideas on what's going on with my stomach, and any ideas on how I can go back to drinking tea that isn't very very weak?
