Seaside, when I quit drinking, I was always irritable. I got angry with everyone and everything. That's normal. Part of getting and staying sober was that I had to accept that I could no longer live my life according to the philosophy "I want what I want and I want it NOW!!!" Gimme gimme gimme. I have had to learn to relax and take things as they come, including accepting that other people's sense of urgency isn't the same as mine.
Day six is great. Keep going.
