Dysphoria
Dysphoria is a state of feeling unwell or unhappy; a feeling of emotional and mental discomfort as a symptom of discontentment, restlessness, dissatisfaction, indifference, depression or anxiety.
These uncomfortable feelings are what bring many back to smoking.
We all had some uncomfortableness when we quit but IT DOES GO AWAY if you stick with your quit.
