5 weeks in and all of a sudden incredibly irritable, depressed, cannot concentrate. Is this normal? Habit: 15/day. 15 years. 

I quit cold turkey. 

It was kind of easy the first couple weeks. Every time i had cravings i just chewed on straws/gum and tried to distract myself. 

All of a sudden about 4 days ago I started dwelling on my past issues and I haven’t been able to distract myself away and ignore it. I’ve become incredible depressed, irritable and angry. 

I figured it’d be normal At the start but after a month??
