Well, I was D for over 3 years everyday, and now I'm C. I think I was pretty lucky when I was D, because even though I had the many personal tortures of trying to build my life around how close I was to a bathroom; I didn't have the pain, bloating, gassiness, and almost continual discomfort that I have now. I used to tell my husband that I knew it was better than C, because I'd had that so bad as a child. Little did I know, I would return to this again!
