Unless you're sitting there listening to something calm and mellow and vaping! I have a huge 20 page paper that I have to have done in 7 hours, I just started it, and listening to the likes of Mozart and popped in a newly refilled black cherry cartridge. Never before have I gotten this much done in such a short amount of time unless I was BSing the entire paper. THANKS E CIGS! You're saving my college tuiton from going down the drain!
