On nightflights back from the US, I always select a seat on the Upper Deck to avoid "through traffic"; the storage bins emulate the "shelf" in F, and give a feeling of space.
Certain seats also have increased legroom, as well, with more legroom than even F provides.
I bring my F sleepsuit and F eyemask, as well as my personal Bose Noise Cancelling headphones (better than those provided by BA).
I have some excellent ear buds from Swiss F which I never travel without.
I bring my own smaller sized travel pillow (but much bigger than the BA F offering), with an Egyptian Cotton pillowslip. The pillow has to be feather and down at the very least; these can often be acquired cheaply on WalMart top avoid carting it out with you.
I spray my seat and pillow with Molton Brown Cool Buchu (available in T5 Duty Free), concentrating on the area where my head will be:

I re-fold the duvet provided so that it is double thickness and matches the size of the bed lengthways.
I rarely need a duvet on top of that, as it's often warm enough without.
Add to this a horse-tranquilliser to aid sleep, or a Unisom SleepGel if whichever ageing relative sources the prescription pills for me hasn't come up with the goods.
Two sniffs of a nasal spray to open up the passages, a couple of eyedrops to keep me moisturised and a water bottle to hand. Sleep like a baby.
I just don't see the point of F on overnight flights.
