I would definitely advise sticking to it longer.
For me, I didn't necesarily notice bm situation get better or worse. I wasn't in a flare when I started though.
For me, I notice biggest difference in how I feel overall.
Eating gluten free: less bloating, less stomach discomfort, less headaches, etc.
I started out saying I was leaning towards gluten free. But now I've embraced it and eat about 90% gluten and dairy free. On the occassion I eat something big that isn't gluten free, I always regret it. I get terrible stomach cramps, etc.
Currently I'm in flare too, so I can relate. Sucky times. :(
Wish you a speedy recovery.
