Thisibelieve, welcome, and congrats on taking the step to admit the problem -- also to visit AA.
I think the exhaustion is normal. I was shaky & sweaty like I had the flu for about a week, and in a mental fog for a lot longer than that. It does get better.
Sugar cravings seem to be really common. I went for lollipops & Lifesavers at first, constantly -- now it's just a cookie or two a day, and ice cream when the cravings get bad. What is it w/ice cream anyway???? God's special compensation to the recovering drunk???
I suggest you stick close to SR -- it's a great source of support!
