I bought this book "FIGHTING PARKINSONS ... AND WINNING, A memoir of my recovery from Parkinson’s Disease" by Howard Shifke. Very interesting alternative therapy, see also his site, www.fightingparkinsonsdrugfree.com. You could also try the mixed approach. Currentlly, I'm using a mixed approach, with my regular meds supplemented by the exercises in his book, that after a testing period of several months, I think they alleviate the PD symptoms (tremor and balance). His exercises, derived from traditional Chinese medicine, are also available for free at youtube. Use e.g. a Youtube search for "Howard Shifke videos." I'd recommend his exercises, based on my practice. They definitely help me to go through my day.
