UCinMI,
While I applaud your wanting to remain med free, and going it solo via healthy alternatives, I think it's going to be tough for you down the road.
Canasa suppositories are so easy to do, and have few if any side effects, and IMO are a good "insurance policy" you can combine with the healthy alternatives.
As for your GI, well, he/she sounds pretty typical: throwing meds at you, without even a discussion as to diet possibilities, or natural supplements which might help. Maybe it's time you shop around for a better GI who is more compassionate and can listen to your concerns?
My suggestion is you stick to the canasa AND do your probiotics, SCD diet, organic homegrown produce, etc....
And as long as you're at it, a few other thoughts: have you had your vit. d levels checked? You can also add organic slippery elm powder - that is nature's mesalamine, and L-glutamine powder (15 grams at least) for colonic repair too.
Bottom line is, as everything in life, you have to follow your inner voice...
Good luck, and feel free to come back and ask any questions of us. We don't bite, and are pretty open minded as BabeintheWoods said.
