I used to drink three or four cans of Diet Dr Pepper a day. Our nurse-practitioner advised against that, and now I only have them occasionally. To be honest, I don’t notice any difference, but since all that diet soda may be bad for me and there’s no evidence it’s good for me, I just keep it an occasional thing.
