Yeah been through this but iv always had probs with shuting down.

Cant remember who said it but dont smoke so much as your mind is using this as an excuse to slep and not to sleep.

I have to take meds every nite otherwise i cant sleep at all.

Also yeah if your have that kinda mind mix it up alittle and exercise for an hour or so(this will help no end trust), but if you cant be arsed, have alittle drink or suning which normally relax's all of your muscle's and mind.

Your suffering from a tiny problem which a big percentage of the world does, so best thing is to jus say fuck it and not give a shit. Easier said then done i know but in the end you will see the results and by that time comes, you would say to urself y was i worrying bout it anyway.

Goodluck!
