Of course he was tired! Cancer is hard! I watched how weak my husband was during chemo treatments! Sometimes he would shake ,be so emotional and tell me he was sorry that he was sick. After 3 years even though he is in rekission,he still falls asleep several times a day. He still has permanent side affects from immunotherapy treatment. He is one of the lucky one who is in remission. The cancer might return or it might not. All I do know is that it can take you quickly or it can take you slowly and ravage your body! I will keep Toby Keith’s family in prayer as they continue to grieve his loss.
