I don’t know what the actual mechanism was, but my step-MIL 25 years ago was a fairly heavy smoker, and checked into the hospital for a hysterectomy. She brought two cartons of cigarettes. They asked her not to smoke before the surgery (not sure why), and she didn’t, but that was a couple of hours, and they’d given her Xanax, or something.
She said that after the surgery, she never wanted a cigarette. She never opened either carton. She ended up leaving them at the hospital “For anyone who wants a pack.” She has never smoked again. FIL was quite happy, because he’d been ordered by his doctor to quit the year before, and was struggling. Now that sMIL wasn’t smoking, he found it much easier.
sMIL stopped taking a blood-thinner, and started taking low-dose hormones replacements-- but was still at a lower dose than before the hysterectomy.
Like I said, I have no idea what the mechanism was, but something happened that flipped off a switch.
If this is a known phenomenon, maybe there is some kind of treatment for “pangs” derived from it-- I don’t mean a hysterectomy-- but maybe something peripheral to the surgery, like a course of gabapentin. I won’t sit here and guess. But you could ask your doctor.
@SanVito Something I just remembered someone mentioning that she did when she quit “The time it worked,” her words, was to hire a professional cleaning service to come in and do a really thorough job on her house-- wash down the walls, and everything. She meanwhile, laundered ALL her towels and sheets, curtains, and so forth. Got rid of every trace of lingering tar, tobacco, ash, etc. in the place, made sure there was no lingering smell.
She said it helped her in two ways: one was that there wasn’t the smell of smoke in the house making her crave a cigarette, and two was that after spending the money to de-smoke her house, she was really motivated to keep it that way.
