Brownie Battle!!!!

I totally forgot that I had to bring a treat to my son's class tomorrow for his birthday.  He told me that he wanted brownies with blue frosting.  He's going to be 5 and that's a big deal, so I decided to make him what he wanted (even if it's slightly strange).  I chose to make the brownies myself because there is a child with a peanut allergy in the class, and I knew homemade brownies would be safe.  Long story short, I fear I've done a little too much batter, frosting and brownie sampling today.
On the positive side, I demonstrated self control and did not eat scoop after scoop after scoop of batter, like I did a few months ago (and no worries, there was no "double dipping" :-).  On the negative side, I probably ate the total of two rather large brownies with frosting.  On the positive side, I'm not calling myself a "lost cause" or a "failure" for the day, which in the past has led me to further binging for the rest of the day and possibly days to come.  On the negative side, there is a weekend of birthdays coming up with more desserts in store, and I fear I might lose sight of what I'm trying to accomplish, and instead get DEEP into a one track mind of "sugar sugar SUGAR!!".
I think this means that not going to the gym tomorrow is NOT an option (I was planning on going anyway, but now I REALLY need to make sure I go), and I am going to have to make a very big effort to get to the gym Saturday, even if it means I'm there at the crack of dawn!!  I'm trying to get rid of my brownie butt for crying out loud, not add a new one!!
