Lists

Sometimes as i'm laying down, ill be thinking to myself of a list of what to buy at the store, or a list of thing to make a certain type of meal i like. ill think of a list when i cash my check on what to spend so i'm not screwed without any money. Sometimes im trying to sleep...and all ithink of are things to do and i'm making a list. some things get pushed off but its always on the list...is there a way to clear my list?
