Hi John We have just returned from the beach. We actually lasted two weeks. The longest we have been away from home since Jerry was diagnosed with this horrible disease. We had a wonderful time at first but the second week was horrible. I started him on his neomycin but it doesn't seem to be working. He has had horrible bouts of vomiting. Some blood which scares me. about the yogart. I have been making smoothies for Jerry for quite some time. At first I didn't add yogurt but have recently started adding yogurt. Your post made me think about the yogart. I just wanted to let you know that it doesn't seem to bother him. I wonder if anyone knows the answer to your question. Maybe Shelly can shed some lite. Hope your not having too much mind fog these day.
