Great job on quitting 
Anger and rage are normal at the beginning. Find ways to keep yourself busy…I played a lot of senseless games on my phone when the urges hit. I would take my break time to play games or do a quick walk around the block instead of smoking.
It does get easier… keep staying vigilant.
