@krsunny1, I want to introduce you to a member who just recently posted a concern about sleeplessness. @stolson1, who has a liver transplant and is beginning to experience a similar problem as you are - sleeplessness. I am also guessing that you have had your transplants for nearly the same length of time.
@stolson1, I have shared a link to the Sleep Health Discussion in a reply yesterday. You might be interested.
Has either of your sleep difficulty started suddenly? Or has it been gradual? Have your doctors ruled out medication side effects?
