i took one dosage last night around 1:00 am. I woke up with upper stomach and back tightness. I iced it, but could not get comforatble. Vomited around 7:00 am. not food, but greenish sputum. This has happened in the past with Percocet for pain. Is tynenol 3 and percocet in the same family? I cannot take NSAIDS, such as anaproxen. any suggestions?
