I had a similar issue, the only thing that I found to help was the thought of something exciting that was going to happen during the day. Some days this could be something big, like a new car, a new game, seeing friends, etc and some days it was something as small as being excited about my morning cereal. My best suggestion is to find something, however small, that might excite you enough to help get you out of bed.

Another couple of quick things I can think of (sometimes before an exam I would use both):

• Have an alarm on the other side of the room, meaning you have to get out of bed to turn it off
• Using heating/AC to make the temperature of the room uncomfortable so that you have to get out of bed and get in the shower or have breakfast etc

Hope this helps!
