Sweet-
I agree with twins about taking it on a full stomach. One thing to remember though is the type of food you take it with. You want to avoid taking Percocet with greasy foods such as burger & fries. Yogurt, applesauce, crackers, peanut butter sandwich, etc. are good ideas.
This may not work for you, but my "ace in the hole" when trying to ward off nausea from meds is eating those Peanut Butter & Cheese Nab crackers. If I really need to I will also sip Ginger-Ale with the crackers, but usually, those specific crackers help 99.9% of the time for me.
Good Luck!!
