Water with bad tasting

Hi, dear people.

I think this is the first time I write here, but I always read them.
I'm male. I'm argentinean. I'm 23 years old.

I wonder if you have any ideas on how to give bad taste to water. Obviusly, I want that feels horrible, but don't do evil to the person.

My greetings to all.

P.S: Sorry if my English isn't very correct.

Add unsweetened lemonade to the water.
Make it strong and no sweetener what so ever.
That will make you pucker up.

I would be careful with things that are 'chemically induced'.
Too much acid can have effects on the stomach.
Better is to look for a psychological agent.
Imagine you hate buttermilk. Then your problem is solved.
Many people do not like the smell of valerian. Etc.
Codliver oil?

Like Brussels sprouts?

Hate them things.
