It's great that you had it easy. I didn't. When I quit nicotine about two years ago, I got kicked into a deep depression that lasted about 3 months (Worth noting: I had a history with depression). I developed panic attacks (and I had no previous history with those).

On the plus side:

1. I quit and stayed quit.

2. I'm mostly back to my old self. No more depression or panic attacks. Not now, and never again!

3. The whole experience cost me so much that I doubt I'll feel much temptation to use nicotine ever again.
