very frustrated!

I'm just at my wits end here. I was doing great and was finally in remission for the first time in over a year. Then in March, i came down with a nasty salmonella infection which totally knocked me into a flare. I was still having problems after finishing the antibiotic course, and my gi wanted me to go on remicade. Well i really didn't want to go on remicade, so i talked him into doing the thiopurine metabolite test thru prometheus to see if my level was within the therapeutic range. I agreed that if it was within range, I would go on remicade. Well, I was way under the range where i should be, so he upped my dose of imuran from 150 to 175. But when i last saw him, he told me that he didn't feel comfortable upping the dose any higher than that, eventhough i really want him to up it to 200, because i'm still having symptoms.
We tried entocort, but when i started to taper off, i immediately flared again. Does anyone know of any good probiotics to try or alternative therapies before i have to get on the remicade bandwagon? Oh and when i retested myself for salmonella last month, since my symptoms weren't improving, it grew out again. So, they put me on a different antibiotic for 14 days and basically scratched their heads, saying they didn't understand why i still had it. So, this has definitely been a crappy couple of months, literally and figuratively. I think I need a body transplant.

I'll definitely try the fish oil or bee propolis. I figured i'd talk to my gi about vsl#3 on my next appointment. I was taken off the rowasa enema, because it started to cause chronic diarrhea and and I've tried the steroid enema many times, and unfortunately, like prednisone, it just isn't effective for me anymore. So, we've been trying the canasa. Thanks for the reply!
