I really don't want to wait until I am disabled before I can retire. I'm 55 and been with the Federal Gov't for 22 years. I've been diagnosed with PD for 5 years. My current symptoms include depression, tremor and lack of co-ordination in my left hand, which are resolved with Sinemet. But the Sinemet causes me to walk funny...like I'm stepping in high cotton. I avoid giving presentations or seminars when possible, but otherwise consider myself a productive federal employee relative to other folks I've seen in the Fed workforce.
