My blood sugar can be.affected.by air, lol.
Watch your numbers close, and adjust.
VG does Not affect.my blood sugar, nor quite a few others I know w D.
The biggest concern is dehydration, we've heard that anyway w D, drink water lots of it.
There is more (IMO) option for dehydration w vaping.
However, my bs have stabilized much better healthier and use less insulin then when I was smoking.
There were some issues at first but I believe that was detox process and not enough water.
9 mos later I'm still vaping and a1c 5.3 [emoji1]
