Saying you want your circadian rhythm match the outside light, then adding that you generally can't get to sleep while being steamrolled in the morning, sounds an aweful lot like you're not sleeping in accordance with your biological clock. Are you aware of delayed sleep phase syndrom?[0]? I have the same "issue" and it took me years to find a name for it, so I'd rather throw this at you, even if you knew.
