It sounds like it's only the night time expressing that is eating into your sleep (lucky you having a 10hr stretch from bub!!) so could you just drop that and up the formula a bit to cover for it? Would you be happy to keep expressing at work?

I just think it could make you feel worse if you weaned completely only to find that once you've caught up on a bit of rest that you could have kept up some of the expressing/feeds.

Anyway, that's just my opinion.. feel free to ignore But as others have said, it doesn't have to be complete weaning.. I truly feel catching up on some needed rest can change your perspective. But we all have to do what we have to do. There's no need to feel guilty for it.

Hope you can feel rested again soon (well... as rested as us mums CAN feel LOL!)
