I once had a problem with a medical doctor saying I was "addicted" -- mentally, emotionally, psychologically? -- to a certain medication I was already taking to deal with high blood pressure. As with several doctors over the years, he considered that particular medication an old one and was wanting to replace it with something newer. Over time I have learned to ask doctors about the possibility of taking a certain medication while allowing them to do the actual prescribing, but I have also managed to find at least one who will give me what I request unless he has a specific medical reason for some different approach.
