A lot of fruit juices are too strong for me also [apple, grape or cranberry for example]. I just cut them with about a third of the glass volume with cold water and if it's still too tart I sprinkle in some Splenda. Works great for me!
Well, I did my taste test... the way my mouth is right now, many of my taste buds fried from the infection, I think Tropicana is the winner... for now. Simply Orange wasn't bad though... but Tropicana was slightly sweeter. I'll drink both, since i have them...
I never buy juice (I'd rather eat my calories than drink them) but my mom bought some when she was here visiting so I'm finishing it up. It's very good.
