Angie,
I have used OJ, Regular coke, frozen custard(very yummy, not worth a d@^^n for BG level though) and glucose tablets.
Personally I metabolize Coke faster than OJ, but I keep both on hand, office and home. I have a faster recovery with Coke, then comes OJ, then comes the tablets.
According to CDE, it's another one of those things where you have to find out what works best for you.
Again, according to CDE, liquids metabolize faster than solids---keep in mind that is a general "rule of thumb."
I'm afraid that you'll have to experiment---

with you as the guinea pig.

The wonderful thing is it sounds like you have a great support system. That is vitally important while you are learning your way around this disease and find out what does/doesn't work for you.
Be patient and forgiving with yourself and you'll soon be giving us information.
