Ok Helena, I would recommend an eGo e cig kit, preferable the ones with the V2 Vision clearos. I believe sweet-vapes sells a kit like this. The V2's are easy to fill and the eGo battery will give you 8 to 12 hours depending on use. The E Liquid is another story, there are so many choices it's best to start out with sample sizes till you find ones you like. There's a ton of vendors on the site so take your time and ask plenty of questions. Good Luck
