Watch TV for a bit, it'll get your mind off trying to sleep.
Or make the room dark, and play on a bright screen, like a DS or phone, that gets you mind off it and make you want to close your eyes.
Sorry but it's tips like these that aren't working
In fact, if these tips in general aren't working, maybe I'm just really asking for names of over-the-counter sleeping drugs >.>
Because unless I'm really tired, when I go to bed, no matter what I seem to do, I take way too long to sleep if I'm sober. Can be hours.
I can be extremely cozy and not move a single limb for 30min - 2 hours, but I will still be awake.
