What time of day works best for taking birth control?

My doctor has perscribed to me the birth control pill. I know that for it to be at its fullest effectiveness, it should be taken at the same time every day. I am rather forgetful, and I am also in college--I get up early on weekdays, but sleep in on the weekends. I also cannot garuntee exactly where I am going to be in the middle of the day or at night, or what time I go to bed. What i am getting at is my schedule is very sporadic. when do you find it most convinient to take the Pill? any suggestions that might help me remember?
