Since I started using ecigs, I've been using prefilled cartos. I wasn't sure how quickly or slowly I would go thru them, since it's only been a month and a half since I started. But I've been going thru them pretty quickly... I assume it's cause I take such long deep drags that the cartos run out so quickly. Plus, before I quit smoking, I was smoking cigarettes kinda like cloves- filtered cigars. They were VERY strong; enough that I was supposed to see a pulmonologist to see if I had emphasema (sp?), an appointment I had to cancel by the way because since I quit, my cough has stopped completely. Anyway (I ramble), It looks like it's gonna be expensive sticking with the prefilled cartos, so I just ordered e-liquid, drip tips, and blank cartridges... just enough to give it a try. So... I could use all the advice I can get on dripping!!! Does it really save a lot of $? Is it difficult? What's the easiest technique? What's the best technique? Is it just as enjoyable as prefilled cartos? Please reply with advice and experiences! Thx!
