Take it from me, you do get used to it. Initially your eyes do water a little but the trick is to squeeze pure lemon juice into your eyes so that they get used to the acid feeling. Start off with diluting the lemon with water and gradually reduce it until your eyes can cope with the pure citric acid. Trouble is though, once you can cope with the tear gas they use the taser which trust me will bring you to your knees. You then get pinned down, restrained with the straight jacket, handcuffed and taken back to your padded cell. Happens to me every day!!!
