I hear some people fix their sleep problems by staying awake much longer for some days then follow a strict schedule.

For me, after physical activity sleeping is much easier but if i over do it cortisol wil make it worse. (I once created an exercise formula that kept me awake long enough I started hallucinating) Spinach does miracles for me, the magnesium folate and flavonoids lower cortisol. Popeye was apparently on to something.

YMMV
