The important thing is to not be "down" on yourself for the relapse. It is ok and you need to tell yourself that. It happens to all of us at one time or another with something in our lives. I am glad the day program is helping you and stick to your guns and don't buy a drink. Before you do it ask yourself "is it really worth it?" When you are tempted to buy a drink think about how hard it is when you relapse!
I sure hope the day program continues to help you and you are able to remain sober

We are always here for you!
