I would suggest rather than stuttering less you'd prefer to stutter easier. There's a little congitive dissonance in saying you're OK with your stutter but want to do it less. This implies you're only OK with a certain kind of stutter and therefore not ok with stuttering as a whole. It's a bit like saying, I'm ok playing baseball, but only if I get a run. I'm glad it's helping though. I hope it continues to help!
