Thank you everyone for your answers (and for just about keeping it civil!). I enjoyed reading everyone's take on it and found it interesting that some people say it doesn't affect their ability to perform their daily tasks while others say it does.

As I expected a lot of people mentioned that the fact they're doing it in the name of Islam/for Allah makes it easier. I'll never be able to understand that, but I guess the closest I can relate to it is when you do something for charity such as a sponsored run or similar, and it's the thought of what you're doing it for that helps you through the pain barriers and keeps you going to the end.

Anyway, respect to you all and Ramadan Kareem.
