The way i understand it is,
that not taking the first drink doesn't mean not having a bad thought or getting aroused.Those things happen many times without us having a say in it.
Not taking the first drink means to not let it go any further than that.
There are many ways to stop it from going further.
Some people have a special tefillah in order to surrender the lust or thought to Hashem.
Some people take deep breaths or think distracting things such as science or philosophy.
I personally use the
blow it up method.
also don't feel bad if the urge or thought hits you without you causing it.It's not your fault.
