Im 15 and I m having trouble sleeping, it usually takes me between 2-4 to get to sleep so normally get around 4-5 hours sleep if that a night and its been like this for about 4 months now, i ve recently started to ache all over and feel ill all the time and can t concentrate in any of my lessons, could not sleeping much have anything to do with it ? ive tried various scents, having a bath before bed, I dont drink caffine or alcohol before bed.
