DO take time to take care of yourself! I also agree that you are role-modeling for your children that it is ok to take care of yourself by napping, reading, resting, etc. Too many young people today are go go go go go all the time especially with the advances in technology. I use meditation techniques when I teach to help my students get centered. Don't feel guilty. I'm sure you have done enough of that. Do what you need to for your sobriety. Your sobriety and YOU are worth it!!
