I crave for sugar alot, and man have I paid alot too for it. Everytime I drink or eat anything too sugary my pouch goes nuts. I have cut all the unnecessary sugars from my diet so now whenever I crave for sugar I can eat a bite or two of choclate without having to worry. I drink alot of lemon juice without any issues and I use organic honey to sweeten anything but very less. Also fasting helps me heaps to keep my pouch stable. I usually have 5 meals from 8 in the morning to 8 in night followed by a 12 hr rest to pouch.

I honestly feel the best when I don't eat. I cannot afford to fast though. Even missing one meal means weight loss, let alone not eating for a whole day. I have trouble keeping weight on if I'm not get 3000cals or more a day. I definitely get sugar craving as well but it's definitely a gas creator. Good luck controlling your appetite.

When you don't feel like eating meals, try organic Greek yogurt (lots of protein) with sliced ripe bananas for the sweetness that you crave. A ripe banana will taste very sweet. You could also add a drop of pure vanilla, cinnamon, or nutmeg to add sweet flavour to the yogurt. Same for oatmeal. Sweet potatoes have more flavour than white potato, are more nutritious, and can help thicken output. Poke holes in a medium sweet potato, pop into the microwave for 5 minutes or longer, and enjoy a sweet snack or as a small meal by adding some protein toppings. I use organic or raw unpasteurized honey when I want sweetness, or I use organic stevia powder from the grocery store. Your orange juice might have been too acidic after not eating for awhile. 

Try not to go hungry; this can mess with your blood sugars and ability to think straight. Even if you eat only small meals or snacks, make sure they are highly nutritious and have protein. Make every bite count, especially if you are not eating a lot of meals.
