I agree with the Swedish Bitters suggestion. Green bitter foods stimulate bile secretion. That is the purpose of eating mixed green salad before a meal.
Take a teaspoon of Swedish Bitters before each meal. You will note the gurgling from the gall bladder within the hour. Artichokes help too. Your body needs a balance of sweet sour salty and bitter. Once a bitter taste hits the tongue digestive secretions begin - from the tongue down to the gall bladder.
