How long does it take to form a habit?

Depends what one is taking. Coke, heroin, crack etc. are easily habit forming because the feeling of pleasure is so great. Before you know it - habit! Cigarettes and alcohol, well, they take a while longer but still addictive. Don't forget that the personality of the taker is important, someone with an addictive personality will fall under the spell faster.

It takes 20 days for ur brain to consider sumthing routine aka a habit, same with breaking a habit just reverse it.

Why am I talking abt habit?

Because I really cant stand CBM anymore. CBM sleeps whenever he wants, spends most of his time sleeping and lazy around on the bed. Once it become addicted.One is burnt out. Without being aware on what is fantasy or reality in time. Hope to see improvement in him! Time is precious, makes use of it, treasure it and don't waste it so easily.
