please do not casually recommend nicotine to people. it is not like caffeine. maybe you are able to use it a little without getting addicted, but that would make you an outlier. it is not a replacement for a cup of coffee in any form, and you're casually suggesting others play fast and loose with a nasty and horribly addictive substance.
God and nicotine gum is so nasty, it makes you burp and has this weird acrid chemical taste. Just awful.
