I drank one can of beer (budweiser) On Saturday Night , the next day I chugged about 2 bottles of water and got ETG tested on Monday. I have a feeling I'm going to get locked up , please tell me I'm good?

Well you have Saturday and Sunday left ,I suggest you keep drinking water.. no juice or alcoholic drink.. water,water and more water

Having said that, you only drank one beer. You should be good to go.
