I wonder if your breathing and general “freeway” space /airway provided max self-regulation. You improved your o2 volume, that alone is huge…and in all the activities of the orofacial complex: breathing, sleeping, swallowing and speaking. I’m a stutter and slp, I’m highly aware and yes, I do have a stutter on occasion and esp when I speak my 2nd language. I find your case fascinating as I’m just getting into OMT work. Thx for sharing.
