Any people whom recently quit cigarettes?

Is there anyone out there who recently stopped smoking cigarettes? I just quit after smoking on and off for about 10 months and it's been hard. I work around smokers so that's annoying when trying to stay smoke free plus I have been eating like crazy    And I am really wanting to not gain weight.Does anyone have any tips and stories on your experiences with quitting smoking?Did u quit cold turkey or use e-cigs?
