I also dual used at first, and I hated myself for doing so. Then I read other people's transition, and if I am not the only one, and there's quite a few of us, maybe it's normal to some of us. I also read other interviews of people who switched from smoking to vaping and all that are published are those who say the never touched a cigarette the moment they started vaping. I can't say I don't believe them, like sure! That's good for them! But it's a little tailored IMO.
Honestly and guilty still, I still smoke. Well, only sometimes and very very little. Call me a troll if that makes any of you happy. But those were situations I feel embarrassed to walk away from. Like my boss gives me stick during an intense meeting to calm himself down. Our old (72yo) ex-con colleague gives me a stick just to chat at the door before going home a week after his wife passed away. And the weirdest of them all, just 3 weeks ago, I forced myself to smoke just to try and see what's there that tied me down for 20 years. I don't feel the urge anymore and I hated the thing now. I moved on. I am without smoke 3 weeks strong. Mentally, I consider myself not a smoker anymore. Although I still have 15 sticks from the pack I bought 2 months ago that I keep just for self satisfaction. Because I think I will buy another pack if I throw that and still use on some occasions. I started vaping 3 years ago, my join date here will never show that.
As for OP's transition, I think you should just relax and not think of what other people will tell yah. It can make you feel anxious and that my friend is another reason to get a stick again. I also think that you just need to stop thinking about it and just grab the vape instead of the pack anytime you feel like smoking.
