Oh I'm sure all have had this happen. One day rockin it out next day just want to veg and not think at all. I see it with Ron everyday. I never know how his day will be until it happens. He may be out in the flower beds digging away and planting and transplanting and rearranging, cutting the grass, weed wacking and the next day in bed all day long getting up only to eat, drink or go potty than back to bed he goes. I don't get upset at all when he don't do anything. There are some days I think all of us would love to not do a darn thing and to be able to is not an option. With Cancer patients you all deserve that day whenever you want to take it is my thought with all you are going thru or have been thru you need your rest. Keep your head up and think positive and good luck!
