Has anyone had their stomach become more upset on Nexium? I feel like I’m going to the bathroom more since starting Nexium. Today is day 6 of a 14 day bottle, my doctor suggest I take the whole bottle but I have to run after eating. I’m staying bland, rice, applesauce, toast, bland chicken breast, plain pretzels, water and sipping Gatorade. I was going normal until Saturday which is the day after I started Nexium.
