Ahhhh,got sleep last night by using a "Tens Unit" I got out of Boots chemist.
It is a small electronic gadget bout size of phone with leads you insert in which
have rubber pads you stick on to skin,which in turn pulsate on muscles where
you place them at different intensites. Put 2 behind each knee on both hamstrings at edge of legs (which I call the hinges of leg),and gradually over
5mins or so,to full power (15) for minimum of 30mins. Have a read in bed
while you wait till it does its thing,then go to SLEEP!
