Oh, What a shame! I was hoping the problem was solved. I've known other people who can't drink tea; they usually just get nauseous though. I drink both and I'm fine, but I don't drink anywhere near as much as you and I don't take asprin.
If you drink EW, it will not only help your stomach but you won't need painkillers. Have you tried it yet? I reccomend drinking some before bed, after you're through eating for the day. Pat.
