Thank U for all the good advice. I do eat a lot of fruit and vegetables and I drink hot tea. 2 days ago I burnt my tongue on hot tea. I am seeing the doctor again on Tuesday for some tests. I will study real hard for the tests. I hope I will pass. I hope the questions are not too hard. I like multiple answers to choose from. I called them and they said that I don't have to study for the test. How am I going to pass if I don't study? Take care and hope to see U soon. Jack
