any pointers for combating sleep disorders?

Not a good choice to make, especially for a logical thinker like yourself!

Are you still studying at the moment, or is school done for now?

I did my Engineering.
Worked with Hewlett Packard.
Quit it after an year.( 11 months)

Are you working currently? I'm asking because stress is always a contributing factor to a lack of sleep.

I have a two job offers. One in government too.
have not planned if I will be taking them up.
Stress is lots.
any pointers are welcome. diet plan, or something like that. or anything that might help me sleep.

Firstly, sleeping pills are merely a band-aid to this issue. Your lack of sleep is due to weeks of sleep time inconsistency, this is causes a shift in your circadian rhythm (bodily clock). To reassure that your bodily clock is reset, you have to dedicate two or three nights to sleeping at the same time, that is, force yourself to go to bed at the same time every night for three days straight - don't worry, it gets easier as the days progress. Sleep is controlled by the release and secretion of melatonin, which is made up of tryptophan (amino acid). This is naturally found in dairy products, such as cheese and milk. Therefore, drink yourself a glass of warm milk one hour before bedtime, and this could help in the production of melatonin.

i do force my self to sleep. But I end up waking up in three hours max.
will try taking some milk too before I go to bed.
Thanks. Will update you if I made progress.
