FireDragon, I hope you read this cuz I had the same problem as you at first when trying to switch over to vaping. For me, it was mental. There was a part of me that was on the, "It just isn't the same", mindset and it pulled me back to tobacco. For me, I had to really dive in...by that I mean financially. I pondered a few weeks to get my mind focused on giving it a real shot, not just a whimsical one, a REAL shot. Then dropped over 200$ as motivation. No one likes to waste money and it's a good motivator, imo.
To cut the urge I agree with most that you need to up your nic level or change the method of your vape... For example, if you find you like cloud chasing (the group of people who love blowing those gigantic clouds of vapor), like I do, I do not recommend upping from 12 or you may find you get migraines from the nic you are getting.
Personally, I find the one of your complaints on the lack of buzz on vaping to smoking can be controlled if you wish. I did it at first but now, I just don't bother. Smoking, like other tobacco methods of delivery give you a quick burst of nicotine. A five minute cig gives most people the next 45 to 60 mins worth of nic they need, creating their level of nic to 'spike' and then drop back down. Nic is a stimulant and that spike is felt as a high to some (tho I didn't feel it cuz I smoked 2+ packs a day of Newports) because of the quick method of delivery. Due to the convenience of vaping, you don't worry about taking the 12-15 drags in a 5 min period so you don't spike. If you want a similar feel, jump to 32 and chain vape. If you are blowing giant clouds, 18 should suffice. Vaping can easily give you the same spike feeling that smoking a Newport 100 while dipping Cope black snuff will...I've done both
But I would like to ask the question, doesn't it feel nice to NOT be bound to the, "OMG!~ an hour has passed, it's time for a cigggggggg!!!" feeling? Scientifically, smoking raises your base anxiety level, so in reality, the nic fix is just making you feel like you would normally. Same goes with vaping, really, you just don't feel the fluctuations as much cuz the dose is more consistent like you pointed out by comparing it to the patch. As for regular anxiety, I have panic attacks, I've been on prozac, wellbutrin, effexor, seroquel, clonazepam, xanax, risperidone, elavil, cymbalta, lexapro, and a few others I can't think of. Outside of actual anxiolytic medications and narcotics, nothing works. I've never had any cig stop a panic attack

I do not recommend using narcotics as a means of stopping panic or anxiety.
