I definitely had mood swings and irritability the first few weeks. Actually, the first week I felt a little overwhelmed, even with little things. I really had to try to minimize the stress (which is hard to do with children, I know!). I'm sure it was a part of getting off alcohol.
The good news is that it's gotten so much better - a little better every day and now I find that I don't have nearly as much anxiety and can even respond to stressful things much better than I did when I was drinking. So, keep going - you'll be glad you did!!
