Kathleen,
Obviously I'm not Dr. Garcia but just wanted to tell you something : Campral has been used in France for awhile now and back a few years ago my ex used it (I didn't realize it until the other day when I got MY prescription and saw the name and the packaging). But he didn't keep off the booze and got back to his old pattern relatively quickly. From what I read, the Campral loses its effectiveness if you drink, which isn't the case with the topamax. So be careful, if you do drink, because the campral will not be effective as it is when you're not drinking.
I'm on campral and I believe that the combination of campral or topamax, together with everything else : supplements, exercise and hypnosis, will really help keeping your cravings at bay so that you don't pick up that first drink. If you can resist, go for it! You'll only feel better and better, and much more in control.
That's my two-cent's worth.. hope it helps a bit.
