Telling him was a big first step. I couldnt stop until I confessed to my GF. I hid it all the time.
First week is the worse, as advised get medical attention if it gets too bad. For me, cravings and wanting got a lot easier after that week. First 10 days went real slow, but after that time returned to normal. Being tired and anxious is also normal, both caused by the alcohol. This too shall pass. Posting and reading here helped a lot. Many people also do AA or Smart or another face to face.
Keep posting and know that we are all pulling for you.
