The fatigue is stunning, isn’t it! And it’s frustrating to have all the tests come back saying you’re fine. Many of us here have been in the same situation. I’ve had tests all over, and nothing. One thing I learned from my long haul clinic: figure out what signs your body sends you before you hit full fatigue ( blurring vision? Auditory or visual sensitivity? Dry mouth? ). If you can figure it out and stop as soon as you “hear” your body’s signals the fatigue won’t last as long. I hope this helps.
