Caffeine: You should avoid caffeine and beta blockers, just because they interfere with the test.

You may also want to ask your Cardiologist for a letter explaining why you might have residual isotope activity in the event you are flying or crossing a border since Thallium, unlike Technetium Sestamibi 99 (the most commonly used isotope in nuclear cardiology), has a longer half life.
