having sleep problems myself,though i know what caused it,
at its worse it started that as soon as i settled down shut my eyes and tried to sleep ,my head whirling with my troubles, i would then feel the adrenalin eminate from my stomach feelings of stuffy air and feeling increasingly hot, i think once you cut off to try sleep there is nothing else to occupy your mind, iv had 2 nights on the run with no sleep at all,then as things started to improve , my body clock was out of sink, like sleeping from 5 am untill 8am or even 11 am,i did at one point try sleeping pills, only for one night , i wasnt happy feeling drowsy while i felt so bad anyway,
i find now, that a couple of paracetomol and a hot milk drink , seems to help wind me down a bit, rather than the sleeping tablet, and try think of anything else other than what troubles you while you try fall asleep
