It's the same advice we gave you about vaping.
Take it slow and easy. Put it down every once in a while, don't be hitting it all the time. Let it recharge fully. Rinse every so often. When you find a flavor you really like, go for it!
And keep hydrated!
Thanks Dave and I have been. Started the planning back in October, looking things up and researching and what not. Finally got all that figured out though and everything set. Should be pretty awesome, plus it was her idea to begin with so can't go wrong there!
