Most of us pace our activities to stop a crash from doing too much but my question is When you do this, does at all actually extend how much you find you can do in a day? I personally find there is a limit that I can do in a 24-45hr period no matter how I break up things eg I "used to" find I could do 90mins cleaning a day whether I did it in 15min sessions or if I did it in a couple of 45min sessions or even as a 90min session (that was before I got POTS). The result was the same with extra 15 min sessions over that total time done even if I had only done it in 15min periods with rest in between would crash me, so I couldnt go really over a total amount of exercise (cleaning) for the day. Do others here find this too with physical activity. That there are daily limits you cant go over without crashing? Do you find this same issue with mental activities too?
