I’ll attest to that.
One time I was sure I was going to wake up the next morning with a top contender for one of my worst. Took 3 aspirin and drank 40 ounces of water. Then each time during the night I had to get up to use the bathroom I drank another 40 ounces. Did that about 4 times. It worked. Felt a little light-headed the next morning but no pain.
Either that or hair of the dog. The water treatment at least spared my the pain.
