Not nice, I know. But at least now you know what it feels like, and you can start to think about ways in which you could deal with the situation if it happened when you weren't expecting it to. It is all part of the training, and it is a stage that you have now got through, so you should be very proud of yourself. Luckily tasering doesn't actually happen all that much when you're on the job, very rarely indeed, it's just important that you know what it feels like just in case you're in a situation where it happens to you.
