I thought my fatigue was age and B12 related as well. I was almost non functional before Xmas. Even small tasks/jobs were just to much. Coming home from work tired is normal. Going to work even more tired isn't.They described Metformin to me as a drug from heaven. I think I’ll self diagnose myself back to 3 a day from my current 1. I can’t tell anymore if I’m fatigued or just old.
I remember when doctors were helpful. They’re anything but now.
My working days were getting shorter and shorter to the point i started to close the business down.
Although i'm still closing the business, this new lease of life is giving confidence i will have the energy to get my next venture up and running. This time i'm getting people to do all the work and i will only manage.
As mentioned above, there come a point/age where you really do have to look after yourself better.
