What are you drinking?

So I usually drink Diet Coke and water, but being pregnant I've been trying to cut out Diet Coke for its crazy chemicals. This was fine until my morning sickness hit level 999999999 and now every time I drink water I'm reminded of the toilet bowl. I've been drinking orange juice and the odd can of full sugar pop but I'm worried about consuming too much sugar. I put sliced lemon in my water but it wasn't great. What is a good drink that I can enjoy by the gallon without vomiting or giving myself diabetes?!
