Stutter gone after starting new medication?

Stutter gone after starting new medication? Hey all, I've always had a stutter and I was diagnosed as epileptic around 2 years ago. Since then I was prescribed sodium valporate to control it, but two weeks ago with the suggestion of my neurologist I started taking lamotrigine as my primary medication for my epilepsy. Since then, my stutter has almost disappeared. My stutter was usually quite bad and I would regularly block. But now, I am mostly fluent pretty much all the time. I wonder if there are any other people here who stutter and who take lamotrigine whose stutter disappeared when they started it, or just anyone else whose fluency significantly improved at the same they began taking a new medication. I should also note that I gave up caffeine (no caffeinated coffee, tea, or chocolate, not a soda drinker anyway) the day after I started lamotrigine, so I wonder if that has had some influence too?
