Sweetichick I did exactly the same thing. I was a pack a day smoker and there was no way on earth I could have stopped both at once. No way.
There is absolutely no hurry to do everything at once.
Put it out of your mind completely for now and then that's one thing crossed off your worry list.
I'm just telling you this as perhaps some encouragement for the future (please don't rush out and do it) but I kind of fell into not smoking after a couple of months. Okay not exactly. I was passing a vape shop and my daughter reminded me I was going to give it a go so I went in, bought the kit and have been a very happy vaper ever since. Yes I know I am still addicted to nicotine and so could be viewed as having given up nothing but I have not coughed once since and genuinely prefer it to smoking. Maybe one day you could try too.........again not yet.
Take care of yourself and remember these things take time xxx
