I would try lowering the temperature in your bedroom. The body lowers it's temp in preparation for sleep and it rises again the in the morning before waking up. In a hot room, the body cannot cool. Our bedroom (basement) is about 55-60 degrees in the winter and maybe 65 in the summer. Sure saves on the heating bill too! Just pile on the blankies if necessary.

We also leave a large box fan running year round. It helps with the cooling and also provides a constant background noise.
