I completed the four-capsule series of Vivotif berna on April 13th, and have been experiencing stomach pain and nausea, especially after I eat. I stopped eating anything spicy and drinking alcohol, but the problem has persisted. I saw my GP yesterday and he was surprised and put me on a restricted diet. I made an appointment with a gastroenterologist, but that appointment is not for another 3 weeks. I am F, 50yrs old, 5"7", 150lbs. I leave for Tanzania on June 30th. Any sage advice or clues?
