I am sorry to hear you are having health problems. It is challenging to manage but you can because it is the best way to honor yourself. As someone that doesn't drink hardly ever I can tell you it is possible to have LOTS of fun in Jamaica without alcohol. The free feeling here is what is so good for our soul. I would definately get all the information about your condition before traveling and purchase trip insurance that included emergency medical service to give you piece of mind. Then come down and enjoy each day with fresh juices, blended fruit, lemonaide, pepsi light, whatever you like. Health is most important though so if it was me I would put my focus on that first before I vacationed. I wish you good health and peace.
