@jodeej Your husband's body had a major trauma, going through the transplant. The body and mind are miracle machines but they still need time to adjust to a new way of being. In this case the transplant, meds and all of the surrounding issues those can cause. Anyways that is my thought on the matter, after hearing that the doctor has ruled out tumor or dementia. That is great news isn't it! I had a sleep study a couple of years ago but it was a problem. Being so uncomfortable [sleep on my back due to probes everywhere] I could not get any sleep and could not get into a deep sleep. It was exhausting. We will look forward to hearing the results of the sleep study!
