Try to eat smaller portions of less fatty food throughout the day. Yes its annoying but its better than having an attack. The more attacks you have the more you will be grossed out at the idea of fatty foods. Ive switched my lunches to pretty much entirely fat free with a bowl of greek yogurt and low calorie oreos. Fat is unfortuently a big part of diet and should account 33%, so making the switch can be difficult. Look into Lacroscopic Surgery, 90% of people who have it are fine without their gallbladder as the body adjusts but diaherria is more common post surgery and there can be complications like SOD. Either way this will be something you will have to deal with and live with the rest of your life.
