First off talk to your Doctor. You could have inner ear problems, High blood pressure or many other Medical conditions.
Peppermint Schnapps! Drank a bunch of it once and darn I couldn't stand up. The whole room kept spinning, and I got seasick. I have never ever drank peppermint schnapps again and this has not happened since. I say don't ever drink Peppermint Schnapps if it makes you dizzy!
There are a number of reasons that can cause dizziness, and it takes a doctor to perform a number of tests to diagnose. It could be something as minor as an inner ear infection, to a brain tumor. See your doctor as soon as possible.
