I have been out of work for nearly two years but even at work I
felt sickly with
a need to sleep, yawning and blurriness, just feeling like I
would drop. Seems when I get this extreme tiredness, my heart/chest starts feeling weird, as if my heart is beating faster with a very wired/jittery feeling in the chest and temples of head. I feel I must lie down. Had an ECG(?) done some years ago, read that my heart rate was slow, like that of an athlete. So hearts ok.
