Topomax doesn't work very well at stopping binge behaviors if you stop it and go back on. It's kind of a once only benefit. The pain blocking effects (along with the brain scrambling) will come back, though. I had to stop taking it because it caused such severe dry mouth that I felt like my teeth were always falling out. After my salivary glands started to work a bit again, I restarted it at a lower dose. My fibro pain was much higher without it, and now is back to a dull backgound noise. BUT I can't ignore hunger like I could before.
My doc wanted me to do a sleep study, but I haven't because the thought of going off all pain and sleep meds scares me to death! You're very brave
Please let us know how it goes for you!
