Well, first off it will be different from person to person. For me, my symptoms weren't very bad, my diet had always been ok ish, and I exercised, and I had only had symptoms for a few years, pretty mild. So I've seen a nearly complete turn around in about a month on the program I've been following (a little different than most people on here). But remember, you are trying to bring back into balance, what you have been putting out of balance for a long time. It won't happen over nite. For some people it could take a year even sticking very close to a good program, just because they have that far to go. There are some good supliments that can help to speed things up, but you have to be careful about what you use. Best of luck to you, if you want me to give any more details about what I've done, then just email me and we can talk. God bless, Mike
