"i started taking tylenol extra strength for pain after a deep puncture wound requiring skin glue. it&#039;s powerful stuff, so i never took more than 1,000 milligrams (2 pills) at a time. the max daily dose is 4,000 milligrams, but i never need(ed) that much; about half of that does the trick for me. i haven&#039;t had any negative side effects, but i worry i may become dependent on it if i don&#039;t taper off soon. i&#039;ve read what it can do to a person&#039;s liver..."
