NO! NO! and even NO!....
headaches are from nic OD or withdrawls from the ciggies
VG and PG on even thier best day can only absorb about 40% of their volume with water... so,... if you vape 10ml of juice and exhale all of the vapor ( all 10ml worth) then you will loose 4 ml of water from your system... 4 ml is about as much as a tablespoon..... I would not call loosing a tablespoon of water dehydration.....
I had not sat and looked that up, figured it but alright.

Still it is a very good thing to remain hydrated. Water is beneficial for your body in so many ways. It helps regulating your core temperature, flushing your body of any toxins, nourishes cells by carrying vital oxygen to them in a form they can readily use. That last one is kind of a sneaky secret.
From what I'm led to understand a lot of medical opinion suggests that cancer may be cells dying, ergo to me at least it would seem if you helped keep cells alive ...

Please though do not rely upon me or anyone here, or any public web forum for truly sound medical advice. Some may in fact be doctors, healers while others may not be. Also, everyone faces different variables. Kind of makes it the best course to see your own medical provider for advice.
Good to know though vaping will not dehydrate one.
