Nicorette side effects : Gas, bloating, belching, burping, flatulence, headaches, severe ear ache, back pain, irritability, severe anxiety, high blood pressure, shortness of breath, sore stomach, can't eat almost any food without it causing issues with digestion. Lightheadedness, fog brain

I went from working out every day to staying home and packing on weight from not working out. I couldn't breathe or I would get short winded or have these episodes that occured where I would feel like I was punched and lost my breath. I don't know if it was the nicorette or not as I suspected gall bladder or gall stones but I strongly suspect it after reading these posts and my symptoms matching others. I have been in and out of the hospital and today just came home from a ultrasound. Not sure if gallstones or not but I am telling you, I am beginning to think it is the nicorette. I am going to do my best to get off of this stuff..been on it a year and I bet my problems are a result of this gum. I think over time these symptoms progess as I have been on it about 13 months. I notice when I start chewing that I will get a small burp. Unfortunately, I will get stressed and chew, chew, chew and I will start burping more. Sometimes, I feel like my whole belly is going to explode and I will belch, have stomach acid, be gaseous, and I will go into a panic attack from the anxiety.

After 3+ years of chewing this gum, I find myself addicted to it. How do I break this addiction and remain smoke free? Help!!

From day one, I have been pleasantly surprised with how effective Nicorette was. I had always just kind of thought it would not help (i.e., that I would still crave the real thing--cigarettes). Admittedly, I didn't follow the suggested Nicorette plan--I still chew the gum and have never really cut down. However, I view smoking as the worst thing in the world to do to yourself, so for me, the gum is one million times better than smoking. And no I haven't experienced any hair loss at all, and I have been chewing the gum for several years off and on, and daily the past 6-9 months.
