Stay away from the coffee and soda. My oncologist said no alcohol, caffeine, and sugary drinks @ all to assist with remaining healthy and reducing the chance for reoccurrence of cancer. However, with digestion, my nutritionist states to cut out soda, dairy products, and high sugar foods/drinks period. But recommends I can drink coffee in moderation but black. So, I do drink black coffee on occasion without incident.
I do not like taking medication unless absolutely necessary.
