Update: I started smoking again. My mental health got too bad, I was really really depressed. I think I did learn from the three weeks I quit and smoking doesn't seem like a great thing now, more a curse I'm stuck with until I have the strength and love for my self to give smoke free life another go. To you out there quitting I commend you. Smoking is not great it's a crappy poisonous addiction I wish I was free from.
