Wow, God bless you and good luck. I'll say a prayer for you and hope that you find the answer. If you do, you'll be helping the ones you love too. You're fortunate to be an RN; you probably can bring a lot of insight and logic to the process of healing yourself. I guess with all you've been through, doing a flush is small potatoes. What's funny is that a simple flush might ended up doing the most good for you. I would do it under a doctor's supervision though.
