Did you get a really good exam in Houston (or wherever) to find out if something has changed with your eyes that needs addressing? Maybe check for increased dryness, MGD etc, then the lens specific possibilities like GPC?
Have you tried moisture chamber glasses over your PROSE? I would hope it would cut down on the frequency of needing to lubricate. Only a short-term solution really till you find out what's going on.
I'm a 6-year veteran of PROSE. I find that at times I need to take strategic breaks to prevent flare-ups. So another short-term thing, I wonder if you can possibly also cut down on lens use for a while and see what impact that has.
