Hi C4G - I agree with the others. You didn't have a full blown relapse. You came right back here and are prepared to try again. A few hours doesn't erase all your months of sobriety.
I had a full relapse last year. A very small (and in retrospect, silly) thing kept me from posting and quitting again. As Quiet said, "If you're not comfortable with counting days or thinking of this as a day 1, then don't". After months of sobriety, I couldn't bear to see Day 1 again. So, I agree with Quiet. It's only important to dust yourself off and continue.
Hang in there. We're here for you.
