I think the sugar thing seems to be VERY common. I know it was true for me, too. I decided that the only way to not crave it was to cut it out completely - it really works. I limit my carbohydrate intake and don't eat any sugar at all. It really does stop the cravings for sweet things.
It is true, though, that it's most important right now to focus on your sobriety. Sugar may not be the best thing in the world, but it's nowhere near as bad for you as alcohol. Give it time and the cravings will probably go away by themselves anyway, as soon as your body has balanced out and is used to your now sober lifestyle.
Congrats on your 52 days. That's wonderful
All the best.
