If you want to rid your body of all the toxins in alcohol, drink as much water or unsweetened fruit juice with lots of vitamin c and in two days you could feel better.

So depending on your metabolism, diet and the state of your liver, a few days.
However if you have poisoned your system with excess alcohol leading to toxicity, then longer.
