Q. Will smoking cessation cause strained bowel movements?

Hello doctor,

My age is 39 years. I have quit smoking, cold turkey after smoking for almost 18 years. It is my 29th day of being smoke-free. Everything was going fine until last 7 to 10 days my bowel movement has been strainful. Few days I have seen very small sized hard stools and sometimes small stool with very little water. I started taking Metamucil. However, the stomach felt bloated severely after eating anything. I sometimes feel a sudden hunger spike that becomes uncontrollable and once I eat, the stomach swells like a balloon. I also started taking one capsule of Triphala to ease out my symptoms. From past 4 to 5 days, I have started feeling fatigue and a very strong one like light handedness and no energy in my legs. I had a sore inside my mouth and that has healed significantly now. The acid reflux is there, especially while making out with my partner I felt food coming up. The consistency of stool after eating Metamucil has been more like rubber shaped long zig zag sausage with uneven and weird cracks and sometimes mucus as well. I feel gas below my stomach and sometimes have to strain hard to pass. I got my CBC done two days back (normal report), kidney, liver, thyroid (normal), Hb (normal), sugar (normal). I also got my FOBT stool test done (negative report). Are the above symptoms cigarette withdrawal symptoms? Or stomach bug? or IBS? I take the following tablets daily. one Magnesium tablet, one Menevit tablet (for sperm health and male fertility), one Omega 3 1000 mg capsule, one 64 Billion Probiotic capsule.

Thank you doctor,

Why do I have fatigue? It is like I feel a bit shaky if I move my head. Is this all part of withdrawal symptoms? Also, I am eating pitted prunes. Is that fine? Do I need to avoid anything in terms of food or anything else? Dairy products? Yogurt. Please advise.
