I wish I could give you some of mine as I sleep like a dead man. Not very much to offer on the subject.

May be a little walk and some food (even a glass of milk will do) before going to bed may help you. Also figure out your bio clock, sometimes you cannot sleep with the times usually set in the families like my father saying its 10, so everyone to bed. May be your sleep timings and lengths vary from the others around you, just figure it out and make adjustments accordingly.

Or is there something else, like some tension or problem that might be bugging you...
