I started simple with a beginers kit that cost me $25.00 and my first flavor about $9.00 this got me started it was about 18ml Nicotine as I was a fairly heavy smoker but before a month had elapsed I'd dropped to a 12 mg nicotine then just a few months ago I dropped again to a 6 meg nicotine and now am about to drop again to a 3 meg level. this has worked for me no patches no gum no expensive medications I've graduated from my beginners kit to an MVP and must say I'm extremely happy if you have other questions please ask thanks
