I'm 22 smoked since I was 14 (I know its very young) I have tried to quit twice using patches the first time and E-cigs roughly a year ago. I found no joy as it made me want a fag more. However three weeks ago I was hospitalised with severe CAP pneumonia for a week and it forced me to go through the cold turkey stage. The first 3-5 days was horrid I was sweating biting my nails to the point they was physically sore to touch but after the 5th day I felt fine and I haven't touched a cigarette now for three weeks ans have no intentions to! Good Luck to the rest of you who are quitting. I thought it would be helpful to others to share my experience and recommend not using alternatives and quitting completely.
