As I see it, there are a bunch of good answers above, but I would put it to you as a choice:
A) your desire/need can control you, in which case you will go nuts trying to suppress it, or
B ) you can control your desire, by recognizing its phases and acting on it when you need to, before it takes over your life and takes you away from other good things you need.
It will wax and wane...and, if you find yourself a good place to act on it, you won't have to suffer consequences like you might if it busts out around the seams of your life. You can also save substantial resources by putting things in a box for next time when you are satiated and start having thoughts about how silly and embarrassing it is.
I myself wear part time...sometimes I feel the need, other times I am a little too preocupied with the rest of my life to bother. But I don't let the diapers and other wierd stuff get in the way of everything else...I just happen to be diapered that day, and get on with it...my wife, my job, chatting too much on line, my house, my friends, my hobbies, whatever!
If you satiate yourself with diapers from time to time, or even all the time, it's really no big deal. It is just taking care of your peculiar self!
