Whacko is correct. This is not about dropping a habit. This is about fighting an addiction. It can be done.
1. Make your promise.
2. Keep your word.
3. Stay QUIT, one day at a time.
Ready is also correct. You have to quit for yourself. UST has enticed, atticted, and tried to slowly kill us for many years. How do you REALLY feel about that? Get mad, stay mad, and turn the anger against your enemy every day.
Reach out if you need anything at all.
