Eight weeks ago I had total knee replacement. The knee seems to be doing pretty well, however I have been suffering from horrendous insomnia ever since. Most nights I get 0 to 2 hours of sleep. I feel like a zombie and have also been suffering from anxiety and depression. I have tried sleeping pills, pain pills, Xanax, meditation, I am seeing a counselor, I go for PT, I am doing acupuncture… I am currently using melatonin and CBD oil. I am completely beside myself and so frustrated. Anyone else experiencing this problem? Any solutions?
