I get up at 5.30am and get home from work at 4.30pm. I’m so exhausted that I struggle to keep my eyes open on the train home. I then get home and within 1 hour I’m asleep on the sofa. I don’t even realise I’m about to fall asleep it’s so quick. I’m so tired that I’m being really lazy and I don’t have any energy to devote to anything else. I go to bed by 9pm latest. Im 31 years old, I have been tested and my vitamin levels are all fine. They used to be very low but I’ve been taking supplements for a couple of years now, I also get b12 injections every 3 months. Is this normal? I suppose my job is quite hard, I’m on my feet all day.
