Hi Distraught.
Stand in front of a mirror. Relax your face. Open your mouth slightly and place your tongue against your teeth. Phonate "NNNNNNNN". Good. Now round your lips and relax your tongue. Phonate "OOOOOOO". Good. Now one right after the other. NNNNNOOOOOO. Faster. NO. Rapid succesion. NO NO NO NO NO!
You have a habit you're breaking. You're used to behaving a certain way and sometimes you have to MAKE yourself change the pattern. Sometimes the person you have to say no to is you.
Now move over a little. I need to share the mirror.
Hugs,
Smoke
