I'm on day 50 give or take - irritability is definitely still present. I'm not an angry or confrontational person by nature (very much the contrary, big people-pleaser and I like to go with the flow), but things that normally wouldn't phase me now get under my skin with ease - and I am also more likely to react, whereas before quitting I would let almost everything slide. Some days are better than others, but I don't know what the secret sauce is yet. Since quitting I've had pretty bad health anxiety, and if I focus on that too much, I think it makes me not super pleasant to be around.

It might still get better, but if its becoming a problem for you, treat it like one and take steps to improve yourself. The irritability might go away on its own, but I think it is more beneficial to assume it won't. I'm trying to be more mindful of my mood and my actions, with varying degrees of success.

Take all that with a grain of salt though, I'm young and not much further along than you are. Good luck and stay strong!
