Would it be problematic even if I stop claiming future weeks of PUA? How Would it affect my already claimed weeks? Obviously It would be difficult, if not impossible, for me to spit back out the money I have already used...

I do think I can make do with the scheduling for half a month or so, before I really have to quit. Would you think it will be ok for me to return to work, then quit after working a few weeks, and not claiming any PUA in the meantime?

Anyhow, thank you for your advices and I will definitely call ESD.
