How do you keep yourself sane and awake during the week when you have to cope with a 9 years old and a 18 years old who always fight for the remote control. 9 years apart and still fighting.

How about taking away the remote and introducing board games? It's a great way to interact and for the family to bond. It would be good to follow the rule where "nobody gets it if you're fighting". Sibling squabbles will always exist, regardless of their age gap. Television isn't a very good way for the family to bond and share, unless they're all watching the same show, which is not in this case.
