Callipos are also great.
Watermellon juice (just zap it in a blender).
I found fizzy drinks helped my burping/gas but filled me up more. I would just drink a little at a time but mostly I tried lemon juice in water, and a little cordial (nice expensive pure one) in water and served cold.

I have EVERYTHING crossed for you sweets. As HB said its hard to stalk/cheer you on ATM so anytime you are ready to post your friends are ready to help.
