I did 36 sessions last fall. After the 16th treatment I felt great and could think more clearly. But it only lasted for 2 weeks and then I went back to where I was depression wise. I was absolutely devastated. It was a teaser to feel so well temporarily and then go back to misery. I completed all my treatments despite the rise and fall in the middle of it all. The TMS doctor insisted I had a placebo effect. I totally disagree. The relief I felt and the change in my cognition was immense and wonderful. Too bad it was short lived. I wish you the very best with your experience.
