How long does it typically take for the exhaustion to go away? I was diagnosed 3 weeks ago today with multiple bilateral PEs (not life-threatening, thankfully), but just washing up breakfast, making the bed and visiting the supermarket meant I had to nap all afternoon. I look after my grandsons tomorrow, and this involves a great deal of walking, collecting them from nursery and their holiday club activity, and, to be honest, I'm dreading the exhaustion - I can scarcely nap when I am in charge, after all! Mind you, my mother, aged nearly 90, has just had a cataract operation and she said I did better than she did - she only managed to have breakfast before retiring to bed for the rest of the morning! We were laughing at each other.... but all the same, it is very boring.
