Hello! OJ is ok for a diabetic to drink. I personally do not drink it because it contains a lot of sugar and carbohydrates. I would say try a small glass and check your blood sugar 2 hours late and make a decision from there. I haven't had a glass of OJ since 2004...I sure do miss it.

Very good questions
Orange juise is very good for a diabetic because it contains a lot of vitamin c
What is vitamin c?
Vitamin c, also known with the scientific name of ascorbic acid, is a water-soluble vitamin with antioxidant properties.
What i suggest to you is to dring as much as you can orange juice to keep you blood sugar under control if possible without using drugs, since they cause to our body side effects. 
A diabetic is allowed 1/2 cup of orange juice because of the high carbs. If your sugar is more than 130, I wouldn't drink any as it will cause your blood sugar to climb. Orange juice is very good for you, and it's always good to have it around when you are having a hypoglycemic event. There is a 1500 rule when you have low sugar. If you have very low sugar (i.e. <70), eat or drink 15 grams of carbs then test your sugar in 15 minutes. Continue this until your sugar is in the normal range.
I'm surprised at the answer above from "about diabetes". Orange juice is very high in sugar (as are most fruit juices) and I have always been advised to either not drink fruit juices except in moderation (1/2 glass as someone has suggested above), but it is a necessity if you are experiencing hypoglycemia (well, it's one method of raising your bg quickly). It's better to eat an orange than to drink just the juice.
