I am to take my grand daughter on already paid vacation leaving july 6. Have had watery diahrea daily for 6 months....also vomiting after eating heavier meal or eating later in evening started couple months ago. Been on nexium for 12 years. Dr just asked me to try Zantac. I ve tried for 7 days but the burning and vomiting feeling in back of throat....touches of vomiting, feeling like vomiting if I bend down to do something then straighter....fluid into throat sometimes. I can t live like this let alone go on a trip. Tried to get endoscopy and colonoscopy but isn t scheduled till end August. What might keep me more comfortable on trip ....I can t go this way. I am 75 and overweight
