So update after a couple weeks of keeping things in check.
At
@Norm's suggestion, I started logging all my food. But that got old really quickly. So I stopped doing that.
But, I have made a few changes which really seem to help.
1) No seltzer, booze, juice or other carbonated drinks. I used to drink 2+ seltzers a day, not that much booze or juice but it all adds up.
2) Laying off the sweets. Probably should be doing this anyway! I had a cheesecake-related episode of heartburn that made me realize this might have been the culprit. Out of the diet has also been Chomps, GUs, sugary beverages.
Things I'm still eating/drinking : Coffee (sorry, I am not functional without it), beans/legumes, spicy food.
So far so good. I sometimes get a minor flare-up of heartburn, but it can be managed with a Tums or 2. Which is a huge improvement!
Thanks for all the input, I'm glad to be back on track and not doing permanent damage to my esophagus!
