Can you die from a Hangover?

Tonight's Mergefest was largely what I thought it would be. As in saw many people, met many people, was out drinking til 6 am. Upon awaking, my mouth tastes like bad Chinese food, rum and cigarettes. The effect lingers after brushing.
I may have to leave the house for consumibles, but I just kinda want to crawl in a corner and whimper til tomorrow.
