Ahhh sleep kitty!!
The amazing thing about the body is you can train it to do almost anything you want in terms of routine.
The lack of sleep you are experiencing is most probably anxiety/stress related. The problem you get is that you wake early or sleep late, then you nap during the day or sleep in etc etc. Then you rinse and repeat. What you do, without wanting to, is retrain your body that this is how you now operate. The BEST thing to do is to not allow yourself to do this.
Ok so. What I recommend is that you set up a routine. Follow it everynight. Avoid stressful or overstimulating activities like watching TV, drinking coffee or tea, playing AO (unless you are token grinding

Avoid using anything that makes you drowsy such as "sleeping tablets". Firstly its not as good as regular sleep, secondly you can get next day tiredness, thirdly they are habit forming and lastly they will decrease in effectiveness over time. If you do need a bit of help to get into the routine use something natural like melatonin (which is naturally produced by your body) or valerian. Do it within your routine for 3-4 days then do the routine without it.
BTW, how long has it been now since your last smoke guys!!! I havent heard anyone breaking their quit attemts!! GREAT JOB. for most of you the battle will get much easier in the coming weeks. KEEP IT UP!!
