I smoked for 30 years. One day I just decided to quit. The first few days were hard, but everyday was easier after that. Drugs are not the answer. As you have found out, the effects of the drug are worse than the smoking problem. Stop the drug and the smoking. You can do it. Let me ask you this: If someone had said they would kill a person you know (daughter/spouse) if you did not quit, would you quit? You would, to protect them. Just quit. You can do it. The mind is a powerful thing.
