Detailed Answer:
Thank you for asking
Tylenol 3 has codeine in it and tramadol is opioid too.there had been an interaction between the two opioid and they have potentiated their effects.upto 360 mg codeine can be used daily for the pain. It with tramadol it's limitations reduce to half .but use for 2 days us least likely to cause this levels.either you have been using it for long or you overdosed or you have been taking it in some other form like cough remedies or energy drinks.i suggest you stop right now and get liver functions assessed.get to an addiction medicine specialist for further management.
Take care
