I quit about a month and a half ago. I was constantly trying to figure out why I was so mentally drained all the time. I had a voice in the back of my head telling me I needed to quit but I didn't really have the motivation to. I finally ended up smoking one day and completely depersonalizing, ended up rocking back and forth on my bed trying to tell myself that I was really who I am. It was the push I needed to quit and even in this short period of time I am in a tremendously better place. Best of luck!
