Diuretic effect: As a result you experience increased water and electrolyte loss which then leads to decreased blood volume leads to dehydration , or hypovolemia, can cause dizziness in addition to fatigue and even fainting.

Better get checked: If this is new and wasn't the case before, or it may be related to caffeinated beverage you had, it might not be the caffeine, wish you well and good luck

"dizzyness" ?: If your "dizzyness" occurs randomly, and with even small amounts of caffeine, the symptoms may be related to an "inner ear" issue with the "semicircular canals" and not caffeine. Ask your physician to refer you to a neurologist or ENT specialist.
