Yesterday was a good productive day... then i woke up today and it was polar opposite.  I am very quick to blame everything that happens to me on PD... Today I was sick to my stomach most of the day... then i was walking up stairs holding a laundry basket and everything started spinning then got black...  i woke up on the stairs and luckily not on the bottom...  i think i was only out a short time my husband was home but didn't hear me.. was pretty nauseous after that but after an hour or so it subsided...  also every day at the same time my calf muscle in one leg starts to cramp up...   i figured all this was due to the PD.. my daughter in law (a surgical nurse) came over today and asked me about all my meds...  when i told her i started simvastatin 3 and half weeks ago she told me to skip the one tomorrow morn and call my doc...  she said she thinks what i've been experiencing is due to that... i never even considered that....   so i am relieved, and we shall see...
