First, you should sue your doctor for having you remove your gallbladder in the first place. Unless the gallbladder is extremely damaged or you have horrendous gallstones there is no reason for removal. Doctors hope it will help, but they dont know.
Are you taking anything like ox bile to supplement? If not, you should be.
You most likely need to change your diet to one with more easily digestible food.
Stay away from gluten, dairy, soy, fried foods, anything acidic.
Drink lots of water.
Take digestive enzymes. i recommend Digest Gold.
Take probiotics. Since its so bad, id go with the Raw Brand 100 billion cultures.
Fats are your enemy so lower them. NO HIGH FAT FOODS.
