Your donor gave you the Gift of Life. A medical team determined that you have a pretty good chance at living a long life with the chance of a transplant. It is important to honor your donor and medical team who all believed in you. Your job going forward is to be a good steward to that Gift. None of us know better than your medical team because that is what they are specialized in and experienced by seeing the success stories(like myself who had a liver transplant 27 years ago - that is longer than your time on earth) and also seeing the ones that don't end up well. Those are divided in 2 categories: the patients who had other health issues that could not be overcome and the patients who choose to operate independently from the parameters and guidelines given by their medical team. Many of those don't make it. If the medical team is unsure of the interaction between tacrolimus and cbd, do you want to be a guinea pig? Is it worth it? Your liver is a precious part of you now, one you cannot live without, it needs to be treated with respect, no experimenting. I wish you well, it would sadden me if you squander this once in a lifetime opportunity while thousands of people die every year because there was not a liver available for them. Please, please - take good care of the Gift and respect all the people who believed in you. Best to you!
