Addiction is a constant, uphill battle. Some days you feel like a rock star, some days the urge is so damn strong, that's all you think about. For me, it was the first two weeks getting away from the demons that haunted me. The cold sweats, the anxiety, the inability to focus, the irritability, it was total torture. While it's not easy, it will get easier, but allow yourself some grace. Fighting this isn't a straight, linear, upward sloping line. You are going to trip and fall, that's just part of it...just as long as you don't stay down.
You will get through this. You got this!
