Avoiding Cheating

I wear the PA5000 at bedtime. My wife unlocks me to go to work because I start getting puffy skin if I wear the device more than 24 hours. Many times I am alone in my office - not many people work there - and I have been getting extremely tempted to cheat (i.e., JO!). So far I have only cheated once and that was three months ago. I told my wife and she just added an extra week to the chastity period. I have been getting 1 or 2 orgasms per month with my permission, but that is down from my pre-enforced state of 4 or 5 per week. So, its still tough. And now we are trying for even longer periods. I don’t know how I will be able to resist! I don’t want to cheat, but it gets so hard to focus on work and the more I try not to think about it, the more I do think about it. And that is the main problem: trying to stay focused on my work! Any wise words?
