I seem to no matter how good I sleep feel tired and drained right when I wake up to the point it feels like my arms are weak or like I don’t want to move, this feeling goes away and I seem to be able to go about my day fine but I really don’t get it ?? Should I be concerned about this weird post night fatigue? The only other thing is I seem to get shoulder and lose neck aches post sleep too like those areas will largely ache with any movement there throughout the day which again has me wondering things but is it simply just to do with sleep and my mattress ?
