Entering multiple W2-Gs

I had 5 W2-Gs over the course of last year totaling roughly 15,000.   Unfortunately I was not prepared and did not keep an accurate journal of my gambling activities, so I can't itimize to deduct any losses despite probably breaking even.  Would it be advisable to simply file those 5 W2Gs, take the tax hit of a few grand, and move on?
