I ve read (somewhere online), that coffee is mildly estrogenic, but it wasn't on that site. That is probably why they say to avoid it while on nbe. Perhaps because it fights for the er's?

I know defacto, the otc migraine pills are just ibuprofen and caffeine. I think someone had told me once that the caffeine pushes the ibuprofen through system faster.

So wouldnt non estrogenic caffeine ( tea) do the same with the nbe estrogen?
