Are you the kind of person who always keeps a bar of chocolate nearby？Perhaps you feel weak or sleepy without your sweets.If so，you may have a problem that millions of SUGAR others have：sugar addiction.
Addiction means using a substance（物質(zhì)） or doing an activity over and over again even though it has bad effects.Playing computer games，drinking，and eating are examples of activities that can develop into addictions.
There are four steps of behavior that happen during a sugar addiction.Step one begins with a strong wish for something sweet.This happens because sugar causes the body to produce dopamine（多巴胺）.It is a substance that creates feelings of happjye.aiess.In step two，even after sugar has been eaten，the need remains and grows.This is because the body becomes less sensitive to the effect of sugar over time.So，it is necessary to eat more sugar.In step three，when a sugar need is not satisfied，the person feels bad.Sugar addicts experience bad emotional symptoms（情緒癥狀）.They also feel physical symptoms，such as headaches，sleepiness and lack of energy.Over time，a sugar addiction will reach step four.This is when the worst health effects of sugar addiction can be seen.Unhealthy body weight and low spirits are examples.
Breaking a sugar addiction can be challenging，but it is important for your health.There are a few things to keep in mind.It's simple advice you probably have heard before.Eat three meals a day，get enough sleep，and exercise often，Choose healthy sweets，like fruit，and avoid salty snacks.These usually cause people to want to eat sweets.Don't push yourself too hard.Remember that lifestyle changes happen slowly.
