That's more-or-less what my sister said. Whatever works. I mentioned this thread to her and she wanted me to add that there was no withdrawal and her behavior didn't change. When she has tried to quit previously it had significant effects on her mood. This time we (her friends and family) didn't notice she had quit until she told us! It was the best Christmas present.
