I dual-used with 24mg in cartomizers, then clearomizers, then a pro tank.
My girlfriend had already moved on to a mod & subtank, and convinced me to order the same.
When it arrived, I loaded up with 24mg juice. She suggested this might not be a good idea.
But that's what I had, so no big deal, I thought.
First hits, a little rough, but OK. Kept puffing.
"I feel funny," I said.
Then the giggling started.
"Are you OK?"
"I feel...fuzzy." More giggling.
"Maybe you should stop."
"OK." Kept puffing.
I can tell you that the 45 minutes or so of fuzzy giggling was not worth the 6+ hours of stomach pain.
