Less counts the definition of addiction than the effects it produces.

Addiction makes its presence felt when you want to get rid of a habit you consider harmful. You realize that some aspects of your life are affected:

• Professional life -relationship with colleagues, relationship with the boss,
• Personal life -as more and more your relationship with your partner deteriorates, family members annoy you,
• Psychological Health -you are cranky, you have many nervous breakdowns, you forget more and more).

Maybe you're thinking that you don't fit in this category as long as you don't have any inadaptive habits like drinking or consuming drugs. But do you ever think about addiction to sugar, gambling, or a person? The addiction mechanism is the same regardless of the way of consumption.
