Thank you. This has been most helpful. I was thinking about the Probiotic and Vitamin D. I go in next week for my hearing and vision screening and then I start! I don't know when I should take the meds. I figure the pharmacist will tell me that. He said he's going to start me on one for a week to see how I handle it and then the next and then the next. I have a trip to NYC and he told me to GO!
