I’m coming up to 51 and am just feeling exhausted all the time. It doesn’t matter now much sleep I have - I’m just knackered all the time. My brain is also really foggy and I’m forgetting names etc that I should know. I’ve got quite a pressured job and feel like I’m struggling with it because of these symptoms. I’m still getting regular periods but they are really heavy. I’ve started taking iron tablets but don’t feel any better. Any advice very welcome.
