I've had RLS and MS for nearly 15 years. Due to my RLS I get roughly 3-5 hours of sleep a night. A few nights a month I would go 30-35 hours straight without sleep. I cut out caffeine staying away from even tea, nothing worked... About one month ago I cut out red dye 40, I haven't slept so well in years. My RLS is nearly gone... It may not work for you but it's worth a shot. That dye is in a lot of food...
