Biologics

Hello everyone, I am 19 and have been diagnosed with UC for about a year and a half now, I was hospitalized for an entire week this summer after trying a more naturopath doctor for a month. Since then I have taken my third round of pred, and started taking 9 pills of balsalazide a day for about 2 months now. It started out good but I started to get worse again and am about to start up on a different steroid tomorrow for 8 weeks. My GI doc says that if these don't turn me around that I may start looking into Humira, which scares me alot. It seems like it's the last thing they want me to try but I know there's other medications out there and haven't tried them all, or diets, however I have been avoiding dairy as much as I can as it seems to upset me even more. Is anyone else on balsalazide? And should I take more steps to help myself while taking it? ie, probiotics, diets etc.

Thanks.
