What Time Do You Go To Bed?

So, i'm trying to create a sleeping pattern for myself because on some nights i can't sleep while on others i can. According to my aunt who happens to be a nurse, she said it might be because i don't have a sleep pattern and i should try getting into one for the next 2 weeks as that's how long the average person's body needs to adjust to a new pattern. Hopefully after that i would be able to sleep easily and have no need for the smelly valerian 2000 which doesn't even work. So what time do you go to bed and when do you wake up?
