Quest of a Shopaholic

How to bring a shopaholic to a halt? I was once a young teenage girl that shopped away most of her paycheck, and now I am a young college student that shops away her small paycheck. I love to shop, and it needs to end before I am out of money or even worse in debit. Shopping has a great part in my life; I enjoy browsing until I find something, and I when there are savings I do end up buying much more. Currently the money I spend is money that I have earned, but soon I will be getting married and our money will combine. How will my fiancé deal with my shopping? I love buying stuff for our house, our wedding, and things for my fiancé.
In the next thirty days I plan to stop shopping completely. I will do the occasional shopping for things that are needed such as food, toiletries, and any needed supplies. As an eBay shopper I will not sign into eBay at all during the thirty days. Any shopping that is done will have to be clarified as something needed not wanted. I have come to the conclusion that I will punish myself if I do break any of my rules. I will have arranged for my fiancé to keep a close eye on me; if I break any rules I will extend my thirty days without shopping. If any times that I do break any rules I will add another three days to my sentence. After the month is over we will discuss how all of our finances will be taken care of after we are married. I do enjoy dealing with money and dealing with bills. I will record the saving within the month, and it will show how much money I have been wasting.
The main rules to focus on; no unneeded shopping, no clothing will be bought, no wasting money on junk food, a minimal amount will be spent on weekend entertainment (going to the movies with my fiancé, etc.), there will be consequences to breaking any rules, and finally try to save as much money during the month as possible. The outcome is unknown, because it may be possible that I am more of a shopaholic then I have known.
