If i had a tylenol last night and this morning can i drink alcohol tonight?

Yes, it should be out of your system. Occasional use of Tylenol in a normal healthy person is not by itself a risk to those have a drink.

No. Alcohol is a poison that never did anybody any good, ever, so stay away from it. It will destroy your brain cells, damage testicular cells that make testosterone, facilitate development of cancer in many organs, cause hepatitis, cirrhosis and pancreatitis etc. There is no safe level of alcohol intake. Quit while you are ahead.
