Waking up has to become a habit for it to get easier.
Meaning you need to make a conscious decision about when you'll be waking up and implement it. For implementation to be successful you need to form a habit and habits get formed in about 20-30 days of repetition.
I've done a lot of experimentation with waking up early and this is the best way to do it for me.
Also, when I was in the army waking up at 5am every day (with periods of only 4-5 hours of sleep per day) for 4 months taught me you need to get up aggressively. Because no matter how tired you are, once you get up, wash your face and teeth you'll be 100% awake and ready to work. It's key is to snap yourself fast from that tired sleepy state.
As for staying awake... I've never had problems with that either. Waking up was an issue till I understood how to approach it correctly.
