To e-cig users..I haven't had a cigarette in 8 months but...?

I want one every day. Every day for the past 8 months! This is the 4th time I've quit, I quit for 10 months last time and started smoking again for a few months then I quit again and its been 8 months this time. So...I ordered Blu Electronic cigarettes with NO nicotine...I dont really know anyone who uses electronic cigs but Ive read reviews and they seem good. I thought that maybe if I could have something that seemed like a cig and even had the smoke (its water vapor) and flavored like a cig it would reduce the urge to smoke a real one for me. I got nicotine free electronic cigs because I dont want to get hooked on the nicotine again. Has anyone tried these and do you think they would help me? I think I might relapse soon if I dont do this...I loved smoking! just not the smell and health problems that come with it! So...if anyone could help me out on this that'd be great.
