Hi, i'am a student doing proffesional course. Am suffering from a very serious issue which is very dangerous to my career as well as my health.. I started smoking from the age of 15. In the beginning, it was 5 per day..but now it is 12-15 per day.. I am not able to sit even for 2 hours without smoking i feel restless and shivering..i usually bunk classes for smoking. The class time is from morrning to evening.. I wish to get rid of this habit. Can anyone advice??
