Nothing silly about
it. I am the same way and only use it when I feel I really need to, but I doubt that using it as your doc recommends is going to cause you to be a dependent on it. I remember years ago, when I got my first one, I used it as ordered by the doc and never developed a dependency to it. I carry one with me all the time anyway, "just in case". LOL!
ETA: I'm glad I could make you feel better!
