Did you discuss this with a doctor? That's the person whose advice you need.
Online diets for medical conditions are often very inconsistent, so get a medically-approved diet.
Now, my husband has a form of acid reflux, and it improved after he switched from regular to decaf coffee. He was told not to eat or drink any acidic foods and juices, so no orange juice, no cranberry juice. (Cocktails are normally mixed drinks, alcoholic beverages mixed with things like juices and sodas, but "cranberry juice cocktail" is just juice with sugar added -- the stuff sold by Ocean Spray. It's acidic.)
Wine is acidic -- no, sangria contains plenty of wine-- BUT, if you want a glass, take a couple of Prelief first. This is something you can buy in a drugstore in the antacid section. You take it before eating or drinking something acidic, and it removes the acid. People who have to avoid acid in their diets find it helpful. If you use it regularly, make sure you get plenty of magnesium in your diet (it could cause kidney stones) and drink lots of water, which you should be doing anyway.
Mild tea is weak tea-- not brewed for too long. You could also try herbal teas like chamomile.
But really, what you need is a doctor-approved diet.
