It's much easier (for me) to go to bed super early and wake up early when going west. Staying awake when tired is easier than falling asleep when not. Though not aren't great for health.

They always say, keep going until you’d normally go to bed so daytime flights out to the Americas are probably easier and then back on a night flight if possible. I hate sleeping on planes though, don’t know how people can - pretty sure it might depend on which part of the aircraft you sleep on though, if travelling economy, which for me that’s always the case.
