@theofilos77 - Typically the reason most people can't sleep is because of the habits they have formed over a long period of time. However, I believe it is possible to fix this without resorting to meds/supplements for the long haul.

two things:

1. try to go to bed at the same time every night, and wake up the same time each day. This way, your body starts to shape it's clock again.
2. take a 10 day challenge and learn to MEDITATE. Try the app "headspace". It really walks you through how to shut your mind off and be at peace with your surroundings.

Do this - and over the next 2 weeks, you should start feeling better.
