Quick Explanation of what TMS is

Forgetting for the moment that the ordinary man on the street might be unfamiliar with the term "transcranial magnetic stimulation", I inadvertantly jumped right into my last post without so much as a hint of what the dang thing was even used for.  So I did get a few "whatthehellrutalkinabout?" questions.
TMS is the new electric-convulsion shock therapy (ECT).  Instead of using electric shocks on your brain, they use magnetic shocks, kind of like an MRI works (I'm sure a medical expert would beg to differ; I'm only interested in getting something to fix me, not exactly how it works).  I had ECT back in the early 1990's.  It didn't work.  In fact, it cut out huge chunks of my memory so if some of you who knew me then and wondered why I didn't seem to remember you'd moved back to Oklahoma City from Washington D.C. and we'd had lunch just a month ago, that's why.  I forgot lots of facts I needed for work.  Lots of life was as if I'd seen a preview for the movie, but never actually saw the movie.  So on to 20 years later:  TMS doesn't require any anesthesia.  You drive yourself there; 45 minutes later, you're on your way to work.  I don't seem to have forgotten anything; didn't even have a headache.  I had 14 or 15 of the minimum 26 treatments required.  I couldn't tell if they were helping--they say 20 treatments is kind of a magic number.  My psychiatrist refused to allow any more treatments because she decided I'd made a suicide attempt and protocol demanded that all TMS be stopped if the patient tried to off herself.  I did not make a suicide attempt, but hospitals and medical personnel really don't care about your explanation, especially when you seriously did try to kill yourself just 4 months back.  So that's how I ended up in the mental ward of the hospital now known only as "D".  I'll save the story of what is and what is not a suicide attempt for another post and you can all vote on which you think it was.
