I'll give brain stimulation therapy in my country a shot lately. I heard one of PWS known of through one of my wechat groups built up by stuttering patients, that one of his friend who also caught stutter had committed suicide bc of his stutter. So I'm relating to PWS more and more and I volunteer to be on human experiments about stutter if brain stimulation therapy won't cause me to be retarded, or dead, etc. Except from these, I would like to pay any costs for experiments and researches. Another of my friends who was also known of cuz both of us have something to do with stutter, has been also contemplating suicide cuz of stutter already for nearly 5 yrs.
