Especially in the last month or two I've noticed I always feel tired. I wake up at 6am and by noon I am half asleep. Yesterday I woke up after 9 hours of sleep (up at 7am) and fell asleep on the couch at 6:30pm and didn't wake up for three hours..even slept through an alarm I set in case I fell asleep.
I don't know what the problem is. I've been eating well, high protein/fat diet, I seem to be eating enough. Even my carbs have been higher than they should be but im still tired. I've found it hard to go to the gym because im falling asleep before I get there. I've been going anyway, I have been trying to lose weight. As far as b12 deficiency. I drink 5 hour energies once every few days and they have like 80X your daily amount of b vitamins, maybe that is a contributing factor.
