When you feel the asshat/jerk/basterd come on that is hurtful to the ones close to you, step back from the situation. Breath. I know it sounds trite. But, you put work into it you will find success. You know what work will do. You also know that is how you get success. Put work into it. We quit one day at a time here. Drink plenty of water and powerade. Energy drinks actually spike your attitude and lack of control. Plus, the dehydration they cause can be horrendous on a quit. Plenty of fruits and tons and tons of water. Be sure to talk with people close to you about what is going on. Look at it like this. You do what was suggested and back up from the situation and breathe for a bit. except, since your wife doesn't know what is going on and why you are doing it she continues the attack/argument/frustrating behaviour. Right? I know it will be tough letting her know. You will feel better if you don't have this invisible elephant between you two.
Congrats and welcome!!!
Just for today, Self.
