Sounds like you have been through hell in the last little while. I start to flare when I go through stressful times in my life too.
I have never had to take Prednisone, thank goodness, so I can't really relate to what you are going through right now, but here is a big HUG for you.
Meds: None so far. Garlic works to ease flares. My GI laughed when I told him and said it was just coincidence.
Diet: Regular fresh garlic, Biobest yogurt daily, Omega 3 supplements, very limited junk food, carbs and processed food, low fat diet. Lots of fresh fruit and veggies (limited potatoes).
