Nissen Fundoplication 3.5 years later question

Hello Ya'll!!!

3.5 years since my first nissen. I am starting to get some very very mild heartburn.

I am wondering if my slacking diet could have caused this?

I was drinking about 5 Venti White Mochas from Starbucks per week. Also drinking maybe 3 sodas per week. Ginger Ale mainly.

Are these drinks that I need to avoid altogether? Not life changing stuff if I need to give them up, just trying to get a feel for the Do's and Dont's. I am sure I have been breaking the rules and will now have to most likely have a re-do!
