How do get up in the morning without having to fall back to sleep?

i am a very heavy sleeper.. i stay with my boyfriend and we both wake up around 8 every morning.. but i can not fall asleep until 12-1 A.M. so i was wondering how can i get up without having the feeling to go back to sleep.. i drink both coffee and mocha but i dont think it helped at all.. so is there a way that i can get a good night sleep and get up early in the morning.???
