I get the exact same thing, and I wish I had your answer.

I find a few things helpful though:
. Watch a movie when you start getting tired. This way, you get gripped, and by the time the movie's over you're thinking of nothing BUT sleeping.
. Open a window. Air improves sleep in general, but a cool breeze is relaxing. It also helps that stuffy, "stuck" feeling.
. Put your pillows in a sitting-up position. This helps, as it fools your mind into thinking "I'm not going to sleep" until you're so tired you just sink into them and crash.
. Camomile tea. Easy on the tummy and so, so relaxing. Just makes you feel calm and dozy.

Sorry I'm not much help, but I hope you sleep well tonight!
