Until you get insurance it is a great idea to start eliminating certain foods from your diet and check results.
1. Dairy
2. Acidic foods
3. Spicy foods
4. Fatty foods
I recommend Calcium (this is how antacids really work), and get yourself some probiotic pills from the vitamin store.
Try eating more raw foods (vegetables) but stay away from tomatoes. Eat grilled foods with just a bit of sea salt. Use only a small amount of olive oil
I hope some of this info helps and good luck man.
