Better to take PIO shot early or late

Hi girls. I am going to a baseball game tomorrow night and don't want to take my shot with me. I usually take it after work between 6-6:45. We are leaving about 3-4 pm to go to the game. Should I take it before or after the game? I am assuming it's better to take it earlier rather than later?
