Relax. It's not the end of the world if you go a little crazy trying to find the right combination. If you freak out about it you're going to want a cigarette!
Everybody's different, so it's hard to give advice, but this is what worked for me. Once I started vaping, I tried a few bottles of overpriced juice from my local smoke shop. I settled on one that I liked, and guess what? It was the ONLY ONE that bothered my wife with the smell of the vapor. So it was back outside for me.
I went to myfreedomsmokes and bought some unflavored nic, and that is what I vaped for 5 or 6 months. My wife didn't complain, I could vape inside the house, and I was spending $0 on juice for quite a while.
The thing about tobacco flavored juices is that they taste nothing like tobacco. And if you're a smoker, what tobacco? People smoke different brands for a reason. It's kinda like having "food flavored" items on a lunch menu.
But here's the kicker. I smoked unfiltered Camels, and they weren't what they used to be either. I don't know what happened over the years, but I noticed the taste changing and becoming less consistent pack to pack. I tried to buy them from the same store so I knew they'd be fresh, but that did no good.
So, for me, even unflavored nic gave me a more consistent experience. It was easy to switch because, accidentally, the cheapest solution happened to be the best for me. Vaping was BETTER than smoking.
I'll buy a bottle of juice from time to time because, frankly, it's a new and exciting hobby and I am curious to see what people come up with. But for the most part I stick to the unflavored for a daily vape.
