IUI and trying to quit

Hi, hope this is the right group for this. I am a heavy smoker, few times a day and really enjoy it. I’ve been trying to conceive for a few years now after a pregnancy loss, giving birth way too early. I did my first

<a href="https://glowing.com/glow-fertility-program">IUI</a> yesterday and am trying my best to not smoke but really want to! Hoping someone can understand how hard it is to completely stop with just the possibility of it actually happening and not being able to find out for the next 2 wks. I already feel cranky, not hungry, and anxious about the whole situation. Any advice or tips? Thanks.
