So far my experience with cigarettes was confirmed, it defiantly affects my symptoms, mainly by making me calmer and less anxious.
But I would not call it a cure, nothing close to it. Relief is rather minor % wise, plus there is a side effect that if I smoke too much of them on the 2nd day of POIS I can feel some of that mild lack of good mood and motivation even on a 3rd day after O. Though I never experience POIS symptoms on the 3rd day.
So I rather picked to throw cigarettes away, there is nothing good about them in general. But nicotine, like in form of patches sounds like possible relief method I might try in future, after consulting medical professionals, but due previous experiences I am doubtful about possibility of any wow effect.
