weaning off Atenolol

What is the best method to wean off 50mg daily of Atenolol after 8 years? BP the past year is 100/70. I weigh 110 and an active 60 years old. Had 2 doctor suggestions: cut in half one week; discontinue next week, or alternate taking one 50 and one 25 every other day. I asked the pharmacist and he said it is ok to wean off but did not give a suggestion. I have improved my diet and take supplement vitamins. What is the best way?
