Agree strongly with sugar N spice and others on here that the Blu is extremely weak! Sorry to stamp on it but Ive been through the same stage when i was quitting my 7.5 year tenure of heavy smoking. Trust me, ive settled for disposables, Blu, NJoy, and other small analog sized ecigs and ultimately found myself turning back to analogs, drugs, alcohol, etc. But i was told by someone while trying to quit that 'Rome wasnt built overnight.' On the other hand, I thought e cigs will NEVER replace analogs. My husband had the same problem (without the drugs and alcohol) but he was brave enough to try the Joye eGo T system that knocked me out of my socks! Vaping for 2.5 years now, we've progressed together further and further away from analogs.
Tip: Definitely get a larger battery and better atty, carto, clearo or whatever your vape style is. Your cravings for an analog with be more satisfied. I havent touched an analog ever since i switched to my first Joye eGo T. I recommend the ego T passthrough battery with the Vivi Nova tank for beginners. Yes, a journey of a thousand miles begins with one step. Whatever you do, dont look back and congrats on the switch!
