I read with interest your experience and know it is extremely rare. It is also important to know that there are far more sophisticated TMS machines out there other than the rather antiquated Neurostar that in one study showed 42% of stimulation sites being too far posterior. There is also the pulse frequency that ranges from 10Hz to theta burst lowering the time to under 10 minutes in some cases and there is even a 3 minute theta. So coming to the conclusion with one machine, while sophisticated protocols and better training are doing great things leads me to this saying. Correlation is not causation. Good luck in the future remember there were those that felt the same way and felt harmed by the Salk Vaccine as well.
