No matter how you feel when you are going through PAWS, the most important thing to know is that it isn't a sign that your recovery is weak or that a relapse is imminent.
I seem to recall fuzzy thinking, emotional swings, pangs of regret for the years I spent wastefully drinking, and urges to drink over things I thought I had learned to handle, like anger...
Just knowing about PAWS and that it could be expected got me through it. Going to Chicago this early in recovery is going to put some stress on you. Stay vigilent over your sobriety.
