I've been smoking for the last 5 years... And I'm willing to quit smoking but I'm not able to do so...I'm smoking 4-5 cigarettes per day... Sometimes 10 per day for 3 months...But for the 1st 2-3 years I used to smoke just 2-3 cigarettes per day...but now it's increasing and I'm also having some issues with my throat... It hurts in between...please help me.
