Oh I know the feeling! for sunrises I always wait for several hours beforehand to find the perfect spot and then wait for the perfect moment! It's nice though, the waiting, it's calm and beautiful^^
I usually do it when the day before has sucked all my energy away by being a really, really shitty day! That's the best time to just stay awake, take the car out for a drive, walk somewhere I've never walked before during the whole night and then find a good spot to take photos of and watch the sunrise So I recommend doint it again soon!
