I understand completely! I lost my medical coverage about 6 months ago after being laid off, and this has been the worst year for me with UC. My Doctor wanted to start me on 6mp, but without insurance, I could not afford to go in every 2 weeks for the lab work. So I did a ton of research and am trying to make a change through diet. For the last 2 months I have been on the Specific Carbohydrate Diet. It takes some getting used to but the diet has helped tremendously. Also probiotics, fish oil, and a good multivitamin.

Good Luck!
