Dude... I'm happy for you that whatever thing you're selling has made an improvement in your life. But whatever it is, I've probably tried it or some variation of it. And yes for more than a day. Frankly, though I do understand that people need money to live, I wonder why you'd be trying to sell it. I mean, if I knew of an effective way to achieve fluency, I'd just tell everyone rather than trying to make a buck off it. But that's just me... someone who has stuttered for as long as I can remember.
