How to watch every episode of lost
It made me
Satisfied 
"I've been following the series since the beginning,but wanted to rewatch Season 4 to prepare for Season 5."
How I did it: I have all previous seasons on DVD. Last year I watched the first three seasons before Season 4 began, but I didn't have time to do that this year. I watched the Season 4 set in preparation for the new season.
