I said the same thing a few months ago; I'm not starting over counting as I only had a "few". I was ok for a while, then bam, I returned to old ways, and very quickly too.
Be very careful about this. I suggest considering it a bump in your recovery and learning how you can handle similar situations in the future so that you don't drink. The next time you might not be so lucky with having "only" 4.
Hope you are well.
