In the future, never exceed 4000mgs of tylenol a day, or 3000mgs in one sitting. Those doses should be even lower if you are drinking alcohol, or if you do so regularly.
12,000 mgs of tylenol is a very dangerous dose, considering it is 3x the maximum recommended dose, and you were drinking alcohol with it.
I'm going to send this to the Other Drugs forum, and they should have some advice on what you can do to minimize damage.
Milk Thistle can help you recover, but I am not sure if you are 'in the clear' yet. I don't know how long after ingestion it takes for acute effects to finish, and if overdose is still a possibility, then goto the ER.
If you took this in a pain medication combination such as vicodin [hydrocodone/apap (tylenol)] please familiarize yourself with cold water extractions.
Here is the current CWE mega thread and FAQ.
