I just happened to get another callback from U of P and got more info. I was told they are doing a study with the TMS and have done 400 people so far with 4 having seizures which is the only serious side effect so far. Also I was told they will give me more info if I pass the initial screening for the study, which I gave today. I will probably wait longer to try it unless they tell me the 4 who had seizures were especially prone for some reason and that I probably wouldn't have that problem.
