No , i never tried this program and i believe it required layrnx microphone and a mobile app .... i was a severe blockers and very hard blocker as well, when i hit a block there is no way i will come out of it , but then i found Valsalva Hypothesis by William parry and it changed my life.. right now even though i do have anxiety and fear but i dont classify my self as a blocker, when a block comes i manage it very easily so i will suggest you to give valsalva hypothesis a try
