I am so happy the mail was early today(for once) and got my starter kit and bottles of juice!!! Not really a problem but one thing I noticed is my first puffs and not coughing? I read on here that when you first use it for the first time you might cough like the first time you smoked a analog. Maybe it is because it is the stuff in the prefilled carts? Or is it I am just strange? Anyway so far I like it, can not wait to try the juices I bought.
