Hello doctor, l have been into the habit of drinking and smoking for the past 20 years. 5 cigarettes a day. One heavy drink per week. Since 2010 both habits became worse and limit exceeded until 2018. For the past two years I am having them at a moderate level. Last week l decided to quit both the habits at the same time. Since 20/07/21, l didn't consume both of them. But l can't cope up with some physical and psychological problems. I am doing it without any medical assistance. Is it really good decision to withdraw both the habits all of a sudden and at the same time? Or should l quit them gradually one by one?
