My Dad has chemo for 3 days (originally was suppose to take for 2days but the doctor thought it will be too much for him so he took it in 3 days). He is still very tired and fatigue after 4 days. Can anyone tell me when the after effects will wear off and he is more to his normal self? I realize it depends from person to person but average that a person will feel better after 3 round of chemotherapy? And anything to help with the side effects?
