What Diet Helps In Controlling And Treating Ulcers?

I have just been diagnosed with an ulcer. I am interested in how to alter my diet. I have 2 meds to use and can look on Internet and get some answers, give me the best diet to use - can I drink coffee (I love a cup of coffee) can I eat a chocolate bar, what kind of sweets, -- you can also tell me about having to give up my favorite breakfast - a Harde's bacon, Egg and cheese biscuit.. Help!
