Thoughts for good health being sent your way. And the advice about the BP cuff and contact with Dr. is great. My DH has HBP, and the Dr. he recently changed to changed his meds somewhat, and gave some great advice on when during the day to take them so they are the most effective. The timing made quite a difference.
Have fun when you finally do get to Vegas. I'm about 100 miles from there, but only go to shop & eat out. The crowds in casinos give me the willies, but there are a few shows I'd like to see, like Blue Man Group and Cirque de Solei.
Get healthy and enjoy Vegas!
