Marling - You probably have a long time to go before you even need to think about it. But when a PWP's quality of life gets really lousy - more "off" than "on" time, or, as in my husband's case, no good "on" time (he was either off or on-with-dyskinesia), surgery looks very attractive. Also, while there are risks, as with any surgery, it's a better surgery to recover from than most. If things go well, the patient is out of the hospital the next day. Friends were astonished when we ran into them in the grocery store the second day after the surgery. We thank the powers that be and medical science for this advance that gave my husband back a reasonable quality of life. Or, as one guy who had the surgery put it: "It gave me back Me." But, Marling, don't even think about it for now. In some tiny corner of your mind you can file away the fact that there's help for later on if needed, but don't let the rest of us scare you. Just live your life to the fullest and enjoy! Margie
