Hmm. In my experience the worst kind of nausea is triggered by beer which is no longer chilled due to being left out for some time. Plus the foam , uggh.
Pigging out after a booze session is another reason, especially if its oily/greasy. Some light snacks about an hour before the booze session is advisable.
also , mixing your drinks is a bad idea in my exp.If y're havin beer then stick to it. I have seen people taking large pegs ,60 ML of whiskey and mixing it with beer instead of soda
Another thing i've marked from my limited experience with booze is that smoking too many cigarettes consecutively while drinking makes your head spin.Its not pleasant , let me tell ya.
I can tolerate fever, headache , bronchitis , The shits , fractured limbs , any thing else you can think of. But Nausea /Vomittting is one thing that is absolutely hell for me, Its horrible, you try to close your eyes and lie down and the 10000 RPM of your brain triggers off..
