I got the ingredients for P&B shakes yesterday and had my first one... took the psyllium and Bentonite separately, but with LOTS of water (36 oz)....everything seemed to work fine. About 4 hours later I noticed a discomfort in my upper esophagus. Thinking that some of the psyllium had become lodged there, I drank another 24 - 36 oz of water, but the discomfort continued and today feels even worse. Does anyone have any ideas what this could be? Perhaps even more important - what can I do to bring about some relief? I tried drinking about 12 oz of club soda but it did not seem to help. Please help!
