I'm grateful I only have to deal with stairs in the vestibule of our building and the many El stops which have, at best, escalators in one direction. It would be very hard to live with them in my house, right now.
The twins seem to be having a growth spurt - being felt 2 - 3 inches above where they were, suddenly, and kicking VERY visibly, finally - which began just as I started to get full much faster and sometimes not want to eat AGAIN (a novel feeling for me, believe me!). Finally realizing this, yesterday, I ate a bit more and had some very nutrient-dense foods. I woke up feeling a lot less drained, this morning. So, I'm hoping that's part of it, in my own case. Not that I'm not tired, but I'm not so utterly desperate for sleep, despite doing almost nothing! :) It feels nice to be more alert and more functional, however far I am from 'energetic'.
Fatigue is virtually always a problem for me, so I do agree with Lynann about trying to cope and do things despite it, without pushing too far or ignoring the body's real needs. Getting outside definitely helps - it's very refreshing. I just have trouble dragging myself out, some days, now.
I'm sorry for everyone to have a hard time, but it does make me feel a bit better that this is a normal, or common, phenomenon. The less the intensification seems related to long-term problems (which I always feel I need to manage better.... like, into not existing!.... which isn't possible), the less I worry, and the better I am able to let myself rest, at need, too.
