I am like RW. I make cleaning in to a workout and crank up the music while I clean. But this past flare that started 3 months ago and that I am just getting over really threw me and I have no choice but to do small amounts at a time. My muscles are fatiguing so quickly.

Make a list of what needs to be done, group things together (like one day I dusted everything, another I did just the floors, etc.), and decide which ones to do. Set a time limit too. I can clean all the counters in 10 minutes or less and then I rest for 10 minutes. For me, it is more frustrating to set out to do an entire room at one shot, start cleaning it, and not be able to complete the task. Then I feel like I have accomplished nothing and then am too fatigued to finish. At least this way I feel like I have accomplished something.

I am sorry you came home to a mess.
