I get that when i try and cut down / Stop for a while (Or when i simply cant get hold of any) Havent really got any tips aside from some sort of excercise to try and tire yourself out and warm drinks helped a little...

Not too sure about any physical, medical evidence linked to insomnia but I do doubt it.

If your trying to cut down then it might not be the best idea to have a J to ease into sleep... (However tempting LOL... And, damn i know its tempting)

Can be difficult but after a few nights of proper sleep you should be good =]
