Going out and sinning

I have a strong faith, and do my best to run from sin. But I find myself pulled to the bar on Friday nights. I keep myself sober but find myself sucked into the atmosphere. I end up making jokes, telling lies and being everyone’s friend. But at the end of the night I realize how much iv sinned and I hate it. Iv asked the lord to help me fight this awful habit of going out. But id like some advice on what I can do as well to do my part in running from this sin. I tell myself all week I won’t go out but wam I find myself in that same old bar stool everytime.
