Sorry to hear of your stroke and wanted to add my best wishes to your health. I have Dragon and would agree it takes practice.
I also wanted to mention a great documentary called Forks Over Knives which teaches how to prevent/reverse heart disease (and other diseases/high cholesterol/etc.)...not that I know what caused your stroke, but there is good info in that doc and not easily found, so might be worth a look. I don't mean to over-step, I just know the info is not mainstream, so not easily found or known, but it can be life-changing.
Best wishes.
