Of course you aren't going to stop smoking
tobacco if you are having problems with the e-cig you have! You may not be getting enough nicotine, but you are also not enjoying the experience. My first e-cig really sucked all the pleasure out of smoking, so I turned to tobacco smokes. It's been three weeks since I started on the e-cigs, I actually got my second e-cig this past Monday, and I still smoke tobacco. I have cut down my tobacco consumption (I was at 2-1/2 packs to 3 packs a day) to about 5 a day, sometimes a few more, but nowhere near what I used to smoke. You may not be able to make the switch immediately, according to the replies on a similar post I made earlier this week.

Get yourself a new e-cig, there are plenty of people who will offer you great advice about this, and give yourself a chance to start enjoying the experience. I don't know much about the Blu, but I think it has an automatic battery. I switched to a manual battery by accident (Vapor4Life's Vapor King), loved the hit and the fact that I could drag from it easily.
Hope this helps, and see you around the forums.
