I don't think that was actually psychological, having the cravings come back after 3 months -- that's one of the very worst times, when quitting smoking -- way back in 1984, I tried quitting, because of the guy I was going out with then, who was absolutely psychotic on the subject of smoking. So, cold turkey quit because I caught a bad case of strep throat and smoking felt like inhaling boiling hot gravel anyway... and after 3 months, I just couldn't take it for another INSTANT, and started back smoking. And I was so sneaky, so sly with eating and teeth-brushing and showering before he got home, I hid it from him for a couple years (it helped that his office was full of smokers, so he had that scent on him when he got home, so never smelled it on me!) -- we even ended up married for a year, by which time it was getting clearer and clearer to me that trying to be someone I'm not, is not a recipe for happiness. But there's this "rule of 3's" you might even have heard of, over at ECF (that's where I heard of it), 3 days, 3 wks, 3 mos, as the big huge danger points when quitting smoking -- apparently a LOT of people succumb at those times. I think it's the actual physical addiction, which some smokers never really get, and then some of us have IN SPADES!
Probiotics do NOTHING for IBS, at least not IBS-C -- but eating a ton of fiber and staying hydrated, that's what helps. If I'm seriously stressed, then sometimes my IBS-C flops over to IBS-D... and probiotics might help with that, but mainly I just try to stay unstressed. I dont think there's any need for "healing," it sounds like you're thinking of diverticulitis or diverticulosis, I don't know which is which, but both/either might benefit from "healing." The big problem I had was appendicitis, topped off with appendectomy, finished up with the most godawful 4 days of my life while my IBS let me know that it was NOT happy about any of this shit, so here ya go, have some VOMITING! A Fate Worse Than Death as far as I'm concerned -- it took me another 3 days before I was starving enough to even ATTEMPT eating! And boy was THAT fun, trying to eat when your stomach has shrunk to the size of a fucking walnut. And everything tastes HORRIBLE because of not eating for a full week... that was what made me decide, hell, if everything tastes bad anyway, I might as well fucking smoke and at least get rid of these goddamned cravings.
I really think it was the Universe, responding to my statements of the previous 4 months when I kept saying i would NEVER smoke again -- the Universe was like, "Oh yeahn ? Well let's just SEE, shall we?" So I'm a lot more humble now, though it's now been nearly 5 yrs since I last smoked; now I just say, "I hope I never have to smoke again," but I'm honest enough to know that if somehow I couldn't vape... I'll probably, almost certainly, be back to smoking again. Really, really hope that never happens -- I LOVE being a non-smoker! And even more than that, I love not wasting so damn much money... on death!
