Whatever it is, congrats on taking a risk! The placebo effect is a real effect. Meaning that by believing you are getting the drug can actually yield the benefits of the drug, even it's not the drug you're receiving. Keep on believing that you can achieve the goals you want to achieve and you'll achieve them. Of course, you can't just believe your stuttering away, but the mind is a powerful thing. Keep the positive vibes alive, friend! Wishing you easier communication, however it comes about.
