question: Hello doctor, I feel listless and tired when I return home in the evening. So much that I cannot exercise on the treadmill. I was on antipsychotics for 30 years which surely caused muscle stiffness and tardive dyskinesia. That could be one reason for the tiredness. Treatment for the above side-effects is now available and I will be starting it next week. Otherwise, it could be fatigue or something which I am asking you to pinpoint. Can you tell me what you suspect to be the cause? And what protocol we follow to resolve it?
