I'm guessing the doc told you, but don't lie down after you eat. In fact best to prop yourself up a bit to sleep. Red sauce, spicy foods and mashed potatoes are triggers too. I did the meds for awhile and they worked soso. I started a health and wellness business and started reading about it. Then I switched to natural remedies including digestive enzymes, stomach soothing teas and added a few herbs to my diet. I had to stick to it for several months before I saw results, but I it's very rare for me to have reflux now.
If the meds don't work let the doctor do his tests or you will continue to worry.......and I think worry contributes because it's all about stomach acid.
