I use the honey right before and right after TX and then brush. As well as a few other times throughout the day, wait half hour and brush. Brushing before TX gives me a burning toothpaste taste. Horrible. The honey doesn't seem to react to the rads at all but I'm always careful to get my lips nice and free of honey before TX because it can make the mask very uncomfortable and sticky.

I used to sell educational weightloss products and a lot of men who were on blood pressure meds needed Viagra. It makes sense... "blood-pressure". If you decrease it with meds you'll probably lose it in other places where it comes in handy.
