Luge to Oblivion

When you have something very potent generally alcoholic or narcotic that hits you so hard there is no coming back and before you know it its the next day you have a hangover from hell and smell like a dumpster. It can be after a few other drinks and Tequila slammers seem like a good idea or that first drink of a Gin Martini on an empty stomach but its the feeling of inability to recover regardless of if you stop drinking that tells you that you have stepped onto the luge and are going head-first to Oblivion.

'We all had four mezcal slammers and that was the start of the luge to oblivion.'
'I remember trying that weird cigarette and then I must have stepped on the luge to oblivion as its all a blank.'
