Adapt your sleeping schedule around it somehow. Natural human sleep cycles actually involve waking up in the middle of the night, being active for an hours or two, falling back asleep and napping during a portion of the day. It's the same reason why almost universally, you'll notice people being sluggish and tired between 1-3 in the afternoon, their bodies instinctually want to sleep. 

It does not matter how well you rest prior to that time, you will notice others being tired, in the same manner, I'm sure many people will instinctually want to wake up between 1-3 in the morning. I know when I fix my sleep schedule by going to bed early, morning waking hours become very natural and fluid.

Idk this has never been a problem for me before. It started happening about 5 years ago. I've tried napping during the day, it doesn't work. Also, soon I'm going to be going back to work and this is going to be a nightmare if I can't solve this issue. I figured it might be something spiritual, because its the same time every night, and I always wake up drenched in sweat and gasping for air. I have terrible nightmares that i have to medicate to stop remembering them. I've tried changing my schedule and all that other shit, it hasn't worked.
