I have a drug/alcohol test tues between 9-5pm. Its fri eve now I'm a female appox 160 lbs. when should I not have another drink? (I do not do drugs)

If you know you have a test, why even drink. If you NEED to have a drink, you also need a substance abuse program.

I will agree, you are in testing because of a problem. Your question advocates not following rules you agreed to follow.

You need to look at this question, really think about it. How important is passing these tests and changing your life ?

To answer question, Thursday should be last drink

YOU shouldn't have a drink period... not this week, not this month... not this year.

Sorry, you are prohibited from drinking....yet you insist on doing it....I have no sympathy unless you take charge of your substance abuse problem and start to deal with it.
