Someone who listens, will do the tests and doesn't rush you when you are in his office! He deserves a big pat on the back. As for your colonoscopy I was fine the next day, maybe a slight gassy, I am IBS-D. As for SFS they have really helped me where my doctor didn't think they were necessary. Good luck with the test and keep us posted. What do they do for the lactose test? I didn't have this one done I just avoid it.
