If anyone who has used the HDR have you had experiences with fogginess in your eye's when your done with your treatment? It last a few hours meaning something does happen. Not sure what it is. But it's wild. I'd recommend getting one if you know how to us. This is a good device to have if ww3 or an apocalypse happens. I get very tired for an hour after it wears off. I'm also going in for a new pacemaker october 5th. So I'm leaving it alone for a week. Once I get my strength back I will go back to it. Cardiac Cath's take alot out of you. Also my birthday is today.
