RD opinion on Tomato Juice

Any of the RDs have an opinion on the pros/cons of tomato juice for post op (5-6 months and beyond)? I do not have problem w/ acidity in foods that some people have. Water does not seem to be hydrating me very well and I was told to drink salt/electrolytes (ok, so i was told gatorade and fruit juices) but didn't want all that sugar. I was looking for a juice without all the sugar that might be a good alternative. Thoughts? Cass

it was given to me right out of surgery(4-11-08) and my doc says mix it with protein. powder V8 too
