I drank 4 beers and 1/2 pint vodka on Sat pm and will be urine tested on Mon night? Should I be worried?

Yup. And a good time to worry about it is before you take the first drink.

Most likely and too late to worry!

Is your "pee test" for alcohol or for ETG? Big difference.

You should worry for two reasons

1. it is very possible you will not pass the test.
2. you know you are tested, and for some legal reason are not suppose to drink. But you still do, which shows a drinking problem that you need to get help with and address
