I'm 45 and the last couple of months I have been suffering with awful fatigue. I can get up ok, do the school run then just want to crash. I've had bloods (not hormones though) and all ok. Also had endoscopy and colonoscopy as I had nausea, all fine. Periods are still happening but maybe slightly shorter. It's awful. Going to speak to doctor this week although I find GPs pretty useless so may go private. It's the kind of fatigue that a cuppa does nothing for and you feel like your eyelids are going to close. It does sound perimenopausal to me. Sugar probably makes it worse so have to sort that out. But I feel 100 years old being this dopey!
