Oh yes, it goes away. Two years post op I can manage to do all the things without falling alseep in my soup, or in the bookstore while drinking espresso, or in the car, not while driving. I used to do all those things, and more. Anything to have a nap and recharge temporarily! As for working, I'm wiped out every night after college, and on the other days as I work for myself, I can pace myself better and avoid Big Fatigue. BF only hiits now if I do too mch, like driving for too long, walk around for a day, shop until I drop or all of those i one day.
Rhonda, This is scary, we all know well what it's like. Be assured that we are all here to help you, so ask away! Knowing is the start of getting control of this! Look into all the options and consider them from various angles. Then make a decision that suits you.
Ciao, Lorenzo
