A fat and lazy person would be clean after 18 hours. Drink lots of water and you should be good in about 8-10 hrs. Your head might hurt.
For A Skinny Person With Fast Metabolism, Can I Pass Alcohol Urine Test In 18 Hours Having 6 Drinks?
If I had a glass of red wine and two whiskey and sevens last night, (stopped at 1am) and I have a urine test at ten, will I pass?
