Tylenol PM 3 Days Before Tummy Tuck?

This should not be a problem.i would NOT take any herbal supplements at leats 2-3 weeks before your surgery.Always like ti keep things simple. 

It is fine to take Tylenol PM prior to surgery because it does not cause bleeding problems like other medicines such as aspirin.  My greater concern is that you stated you routinely use this product to help you sleep.  It's not uncommon to have sleep disturbances after surgery, and if you take this to help you sleep in addition to taking narcotic pain medicine (which already contains acetaminophen), the large amount of acetaminophen has the potential to cause liver damage.  Please discuss this with your surgeon.

Hello and thanks for your post. Tylenol is considered safe before most operations. You should check with you PS pre-op instructions or the office before consuming anything that was not specifically discussed with your doctor. Best wishes, Dr. Aldo.
