The best way is to purchase and install a programmable thermostat. These thermostats are designed to raise or lower the temperature settings at times that you specify. So, you can set the thermostat temperature to raise just before you wake and you may find it much more comfortable. Make certain you buy the correct thermostat for your needs.
If you cannot afford a programmable thermostat, try turning your thermostat down just a few degrees, perhaps 4-6. This may be more tolerable for you.
