Too much Pu-Erh = stomachache?

Hi,
I just joined this forum, but since I work at Teavana, I do have some insight on Pu-erh tea! It aids in digestion, so by drinking multiple cups of it, I can see why it would upset your stomach. Too much of something that aids in digestion would have a negative effect, I believe. Pu-erh is also related to black tea, and I know people who get an upset stomach if they drink black tea. Lastly, Pu-erh has caffeine in it, so you might be responding to that as well. I love tea (David’s Tea and Teavana in particular), so if you tell me what flavors you like, I’d be happy to offer low-caffeine suggestions that aren’t Pu-erh. Hope this helps!
