one thing at a time. Try giving up the cigs when you are stronger. If you give up to much at one time your cravings with become too much. I gave up drink and when time had passed and I was stronger I gave up cigs. I found it impossible to just give up drink on my own. Do you have any support? Congrats on 6 days. Its probably better to make the days count instead of counting the days ...at the start. at least that was my experience.
Good luck.
