Will Diet Coke make me gain or lose weight in the short term?

Any jockeys or prizefighters in the house? I've read repeatedly that Diet Coke and other diet soft drinks have both sodium - which makes the body retain water - as well as caffeine - which acts as a mild diuretic. Which effect is greater? Will drinking a diet soda cause a net gain or loss in your weight a few hours later?

First off, I'll admit that this is totally prompted by an upcoming Weight Watchers weigh-in. I'm not trying to game the system, but I would like to be sure I'm not going in there carrying any extra weight. It sure seems like when I have a Diet Coke (after drinking normal water), I end up going to the bathroom a lot more often. So in a hypothetical situation where you wanted to weigh-in as light as possible, would it be better to A) just drink water, B) drink water and a bit of caffeine, or C) drink nothing at all? I've done some Googling and while I can find references to both the "water retention" and "makes you pee more" effects, I can't find anything that suggests whether they cancel each other out.
I'd just like to stress that I know Diet Coke isn't healthy and if I were a truly good person (that was sarcasm), I wouldn't drink it at all. But dammit, I've lost nearly fifty pounds in the past year and I need to feel like I have one tiny vice left. I've just always wondered whether I should cut it out on Weight-In day or not. (I know that the net effect is likely to be miniscule, and I'm truly not the type to obsess about 100g... but I just wondered.)
