I've been vaping for months now
Like TFA Double RY4 and brewed up 120mL of 10mg, 500mL of 7mg and 120mL of 0mg nicotine. Have around 7 flavors laying around and if the RY4 is weak, I just add a drop or two of flavoring (apple, cherry, chocolate, cappuccino etc) for a change of pace. I use 60% VG ratio and a Pro Tank with EVOD head and it's close.
My issue besides flavor weirdness is getting a setup I can drop, work in the garden with it in my pocket and step on. So far, broke around 3 Ego types but am looking for the right Mech. The Kamry K300 telescope with metal shield that screws over the pyrex clearo seems to be what I need. Use AW 18350 IMR batteries, a Kamry "fuse" and a 1.5 to 1.8 ohm coil should be about right.
Cost wise, I'm spending half what I would of spent on cigs--not a bad deal! Next week I'll get the K300 (or K100 if they screwed up the K300) and not worry about gravity testing my PV.
A buddy of mine has been vaping for 3 months, he feels down that his menthol cig habit fell from 1.5 PPD to 0.5 PPD... The guy has about 30 different flavors of juice and generally uses 4 flavors per day. Relax, it is a process so don't think all or nothing...you'll find the right level of balance between vaping and cigs...eventually it will all come together so just stick with it.
