Jody, for night please try Muro 128 ointment. It's available at the drug store without prescription. I don't mean Muro drops, but the ointment. If you are having erosions (and I don't know for sure you are) this might help more than anything.
It's sort of a soft ointment, not stiff like Refresh PM. It's not ideal, but for the worst cases, I'd suggest you try this. You may have to ask the druggist for this as sometimes they keep it in the back. I've 8 years into this stuff after lasik and I still use Muro sometimes (even during the day) if I'm terribly dry and afraid of an erosion. You already have others' best suggestions. My doc said I could use it forever if I need to. I also use drops.
Don't trust any refractive surgeon with YOUR eyes.
