I'm sorry to hear that you are at the beginning of your M&P addition.
You need to enter the M&P anonymous 12-step program before it is too late.
The meeting will go something like this:
"Welcome (your name here) to M&P anonymous. Repeat after me... I recognize that I have a problem. I will not buy any more M&P's."
I have personally fallen off the wagon a few times. I'm sure that someday I will be able to stop buying M&P's... or not.
