Ok so I know that no one here can answer but perhaps some suggestions.
I'm 40, I work part time. I struggle to stay awake for the whole day and regularly have days where I'm so sleepy and low in energy I struggle to do anything. Have 2 children but they are older so not waking me up at night.
I sleep really well, go to sleep by 10.30pm, up at 6.30-7am, sometimes an 8am on the weekend. My diet is fine, I'm not overweight.
I've had full blood tests recently and everything was normal, I take multivitamins too.
I do have a bit of stress due to a hectic schedule outside of work and it's like when I sit down I just want to fall asleep.
Any ideas?
