Yes this will change. Congrats on 1 week btw. Have you had your blood work done? Usually we Archie's have a lot of vitamin deficiencies so you can find which ones and supplement. That helps me a lot.
Normally in detox (I've er done this a few times, ehem) I'm a manic mess. Can't eat, can't sleep its awful. This last time I was beat and couldn't stop eating. That was way better quite frankly. Took about 5-7 days to get energy back. I also started exercising which helps me tremendously. I'm, um, 28 days I think so I've cut out the sweets. Day 2 no sugar. In the long run eating really healthy helps me stave off cravings for alcohol.
Hang in there.
