I'm not sure if age has anything to do with it. But I understand what you mean about not feeling like yourself. I think that is the hardest part for me is trying to explain the way I feel to my doctor because he doesn't understand what I'm trying to say. I'm going to get mine taken out soon and go back to the pill. I figure if it is what is making me feel bad then it will solve the problem. If not, atleast I don't have to worry about experiencing all the other horrible side effects others are having in the future. Good luck to you!
