Hi, I'm new too. I will offer my newbie tale: I started with a disposable blu. It's a great way to "test the water." I liked it, got a blu rechargeable. All was well for like two weeks. I cut down the analogs but still had a couple a day (down from around a pack) in your case this may help you get through a week but you may revert to analogs on weekends. I splurged and got an eGo Twist and haven't touched an analog since.
My recommendation is to try a disposable. If you like it, skip the rechargeable "cigsalikes" and get an eGo Twist. It's still slim and moderately compact, but with a little room to grow. The ability to put different tanks on it, adjust voltage, and maybe move on to a bigger mod and keep the eGo for when you want something smaller, that's my plan.
I'm no pro by far, but I was recently in your shoes so this was my experience
