Ok. So i've recently learned that i love vaping! Using manual 510 regular sized batteries and cartomizers. It's the only thing i've ever found that's conpletely replaced regular cigarettes. here's my problem. After my 7-10 puffs to get my " i need a cigarette" fix, i have trouble putting it down. I'm considering getting some no nic "rainbow packs" to sample flavors and from what i've read, an atomizer is the way to go. Do i have to clean the attys after every different flavor? currently i switch betweem 2 flavors i like and always have a carto of each ready to go. Is that the more effiencient use of juice or does the stuff dry fast enough for it to be worth switching to attys?
