3 weeks post-op. I love,love ,love my coffee and like to use high quality Beans. I started with half strength peaberry beans and was able to drink a few glorious ounces . Doesn't seem to bother me as far as making me hungry, upset tummy.. etc.. I'm on week 6 now, drinking full strength peaberry ( low-acid) and my favorite Kona beans ( not that crummy 10 % blend ,but the real 100 % deal from back home in Hawaii) No problems and the doc says it's fine. His only concern was dehydration since it's a diuretic, but I also drink a couple of liters of Water a day so it's a non-issue. Here's the place I get my supply from if anyone else is interested. http://www.koacoffee.com/
