Is it o.k. to say "Good Morning" if the sun isn't up yet? I guess so. 3:30 to 4:00 a.m.; that's my witching hour these days. No matter how tired I am, I wake up at that time, my body just taut and vibrating like one of my ukulele strings. Can't sleep through that!
I wonder why certain positions make the symptoms worse? Lying down always makes the tremors and rigidity worse, and sometimes the dystonia and dyskinesia as well. Unfortunately, I've never had the knack of sleeping standing up! Sometimes I can manage it sitting down, but that's usually frowned on at work...
The good news is that I get this short quiet time to myself while the rest of the house is still asleep. Sometimes I share the time with the four-legged denizens of the house; the dog curled up by my chair and the cat on my lap. Sometimes they just look at me in disbelief as though to say "3:30 in the morning? You gotta be kidding; the birds aren't even up yet!" and go back to sleep.
I do enjoy these solitary pauses before the day starts (after I get over the annoyance of being rousted out of bed by Old Man Parkinson). There's always a silver lining.
