Hi DoubleJ
Welcome to PC. I'm sorry to say I have no experience personally or relationship wise with anyone diagnosed with IER. From what you've described, it does seem to be a horrible disease. I've posted a link from The Mayo Clinic with some information if you're interested. Hopefully, there are some members here who can directly respond to your question.

Good luck and take care,
