@testlady I am sorry to hear you are having the fatigue, but as the others have said, it is quite usual with the antibiotics. After my body adjusted, the day after each dose was worst, followed by a day when I could do a little. I used to be active at a task for 15-20 minutes, then rest for 30-40 minutes and try again. Most days I could manage 2 hours of light activities doing that, but by 4 pm I was "on the couch." I got very good at figuring out what was essential, and at asking for and accepting help.
