You already did 2 things that were very good ideas - coming here with your drinking thoughts, and also "playing the tape forward"....and recognizing that it will never be "Just one".
Sometimes there is a "pink cloud" in very early sobriety where everything feels great, your body is getting healthy again, you are proud of your hard work, etc. Then reality suddenly reminds you that life is going on...which it always does. Accepting that we'll have bad days no matter what is important - and seeking extra help on those days is even more important. Be well!
