Stick to your first thought. Being a child of a parent that abused alcohol I can feel for your children. And also being a parent myself. My kids are my first priority. As a child I seen that my mother was stressed, frustrated, and tired by my fathers' behavior. When she was going through it she made less time for us. Or she wasn't fully there because she was contantly worrying about him.
So what I am saying is that the kids will remember and can be affected by this time. So think about them as your support. Make yourself whole for them.
