I have Been through a very bad spell that should have ruined my marriage, but my wife stuck through my insanity.  That was neupro.  Thankfully, a couple of years later nuplazid came out and gave me a tool I could use through recovery.  Before nuplazid, I tried dbs to hopefully get away from drugs causing problems.  After about 3 years, I finally got settings that really helped me stop being so dependent on sinemet to walk and think.  I was using amantadine when I was on neupro and started sinemet.  It was generic and caused some skin side effects.  MayBe it works better now for me because I had a serious infection from the dbs and now my brain a little different after that near death experience. Or, maybe I am blessed this time; or who knows.  All I know is it is working for me and I am much more in tune with changes in my body and mind.  Before I was just thinking i needed to get back to my old self and there were a plethora of things to try.  I was so used to pushing myself, but after years of tough trials, I am much wiser.  
Thank you for your concerns.  I appreciate the wise caution.  Unfortunately, I learned the hard way and my family now have their own scars from it.
