Three days ago, I took 9 tylenol (500 mg each). Took 5 around 9am then 4 more around 1 pm, due to severe headache.

Wondering if:

a. Did I destroy my liver? I don't normally take tylenol at all, usually just advil.

b. Can I drink alcohol tonight? It will have been 3.5 days since I took the tylenol, and I rarely drink anymore.

Thanks in advance.
