Tylenol and other similar over the counter pain medications are not strong enough and you'll end up damaging your liver. It would have to me something alot stronger with respiratory depression like morphine and fentanyl. Even then, still a good chance of surviving since lethal dose will vary. Combine them with benzos and alcohol and it'll be more likely to succeed. In general, ODs aren't the most reliable and there's also the issue of nausea and vomiting.
TL:DR. Tylenol won't work and if it did, the dose would be ginormous.
