Yes. My stuttering can be intense and some times not intense. I often resort to written communication over talking over the talking on the phone. I’ve communicated in hand written form on paper to avoid stuttering as well. Your question about using a GSM to avoid stuttering really got me thinking. Many people quite often prefer a GSM’s text messages who aren’t stuttering. But as far as me, I only do the texting to avoiding stuttering part of the time. As far as it being a bad idea, I say it depends. If having to write down what you want to say on paper or your GSM to the point it is ruling your life I'm not sure that it would be a beneficial alternative.
