In the past, my attempts were only half-there. A few weeks ago I fell and bruised my face (which fortunately is almost fulled healed) and that inspired me to stop for good. My biggest temptation is bars so I just need to continue to avoid them.
A reason why so many of my attempts are only one week is because Fridays are a huge problem. But one thing I am doing differently is taking a cab/bus immediately after work on Fridays to avoid having to walk near bars.
