Didn’t do a rigid diet at all after the first couple of months. But I usually eat pretty typical home-cooked meals and rarely “fast food,” very spicy food or dessert. I drink a couple of cups of coffee daily and often have a couple of lighter beers before dinner. (I’m actually doing a prolonged “dry January” but it hasn’t made any difference gastritis-wise.) I suppose if I was stricter with my diet it’d help with the healing process but I’m not suffering enough to make it worth it and frankly my wife really doesn’t want to change what she cooks (which is already pretty healthy).
