Thanks for the replies!
I definitely will increase my water intake overall, but especially while I'm vaping.
Last night was probably the worst. I was sitting on my couch, watching TV, vaping away (something my wife would NEVER let me do with analogs), and my mouth became horribly dry. I drank glass after glass of water and it didn't seem to help. Running to the bathroom every five minutes presented its own problems.
BTW, speaking of vaping inside, I LOVE how I can puff away on my Blu like a cigarette on my couch, in my home office, car or wherever and not have to worry about the smoke and awful smell of analogs lingering around. Even my home office, which doesn't have the best ventilation (in my basement), the smell from my vaping disappears very fast. My wife has a sensitive nose and she can never smell it.
But I digress. The only negative of vaping I've found so far is the dry mouth. I can live with that. More annoying than anything. If it gets me to drink more water and stay better hydrated, then that's just one more benefit of vaping. Lol.
