Hi, I came into this discussion a little late. Hopefully by now you’ve gotten some relief from the bone and joint pain...and some sleep! While I I didn’t have a liver transplant, I did receive a bone marrow transplant. We share many of the same anti rejection meds. Tacrolimus being one of them. That medication, along with a few others, are known to deplete our bodies of magnesium fairly quickly. I have to take supplements daily to maintain a normal level. A low level can produce similar symptoms along with myriad other issues. Do you have routine blood draws frequently? If so, maybe mention to your physician to add a mag level to your next labs. The level should be 1.7 or higher. Best of luck to you! Lori
