I just marked the 17th anniversary of my dx in August. I too was on Azulfidine and Folic Acid for the first years, then along came Pentasa (for me it was the mid 90s). I was glad because the Azulfidine made me get sunburn even faster---literally 1 minute in the sun and I was scorched. I had a couple of rounds of Prednisone in the mid 90s to 2001, but nothing really long term. I think my surgery kept me from needing more care---my opinion. Wow I just realized I have only taken 3 different meds in the 17 years.
Mostly I just cared for my CD by not eating anything that ever hurt me ever again. I was completely veggie free, only had bananas for fruit, never drank milk, avoiding any high grain items, only meat I had was chicken. Hmmm...since I started eating again, I have headed into a flare. Time to restrict the food again.
I have not tried the "bigger meds" yet. I am still weighing the thought as it seems you are too. I have to decide by 10/2 if I go to 6mp/Imuran. let me know how it goes for you
