MizBee,
I would strongly urge you to look into LDN, low dose naltrexone.
It put me in remission.
BUT you have another reason to take it too: your malignant melanoma.
LDN does not suppress the immune system, and it's been shown to help put cancer in remission too.
So, imo, for you, you'd be killing 2 birds with one stone.
If you are interested in reading up on LDN, there's a post on it on the UC Resources page (towards the bottom).
And if you still need more info, email me and I"ll be glad to help you.
BTW, regarding your depression and UC actuallly, , when were your vitamin d3 levels checked last?
BOth have high correlations to low levels of vitamin d3.
