What are the most common side effects associated with nicotine gum?

Nicotine gum, when it is chewed too fast, makes a little more nicotine go down the throat rather than just be absorbed in the mouth, and it can cause irritation, hiccups, and heartburn; so you don't want to over chew the gum. It can also cause irritation to the mouth, which could cause blisters in the mouth. Most people, which is the vast majority of people who use the nicotine gum, get used to the sensation in the mouth and it doesn't cause very untoward effects. Most people tolerate it pretty well.
