Been out of rehab for a month.

Congratulations on entering recovery. The urges will come and go, but they become less frequent and less severe if you enter and stay in an after-care program like a 12-step program. You will find infinite support, understanding and encouragement in a good group. They teach us how to recognize the triggers that cause the urges, and how to navigate through them and overcome them. The programs work if you work them. I wish you the best of luck and prayer in you sobriety journey.
