By the way, once your ulcers clear up you will be able to resume normal eating and coffee habits. The stomach is one of only 2 organs that can repair and regenerate themselves. I have had 3 or 4 bouts with ulcers lasting years. Once they healed I was back on coffee, juice, etc. Hopefully your ulcers are the ones caused by an easily identifiable infection (forget the name, blood test identifies it) and a month long course of several antibiotics will cure it.I am a steady coffee drinker, always was and always will be. Only one of my ulcer attacks was caused by that microorganism, the other 3 and my years of spastic colon were caused by nervous stress. Stress induced ulcers are harder to clear up since if you knew what was causing the stress you could deal with it! LOL The ulcer that required antibiotics cleared up very fast - only a few months.
Hope your new diet and doctor's prescriptions clear the ulcers up. Milk is good, goat milk is better. I drank Nubian and LaMancha unpasteurized milk constantly during my ulcer problems. Higher fat content in the Nubian milk. Also, higher butterfat content than commercial cow's milk since it was not separated. I think the high fat content helped to soothe and coat the ulcers.
Some people currently recommend pasteurizing goats' milk before using it for house milk but we never did. My children drank unpasteurized goat's milk all their lives and they never had acne or pimples during puberty either. The only time I pasteurized and heat treated colostrum was for the goat kids even though we blood tested for CAE annually. With careful testing and pasteurizing we had a clean herd.
