It 's mono. Now this is the 4th or 5th time I've had it since I was 11. When I was 11- it was the worst, all summer. I couldn't rodeo, show my horse, swim or anything. This seems to be the 2nd worse - taking a shower and going down to do one load of laundry and I am tuckered out. Guess I best get my hiney back to the couch and rest. Thanks to all of you for the prayers.
