I wouldn't do it if I were you. Munchies' answer is good, but gonna add some more things.
One is that for some reason, soda seems to stay in the body for longer than water does, for some reason. And when that happens, you'll probably end up eating less.
Most soda in America also uses high fructose corn syrup (HFCS), which is horrendous if consumed in high quantities, and if you do what you want to, it'll be too much. There's the fast effect on very high blood sugar, but there seems to be something almost unique about it too. It's much worse than regular sugar, and it doesn't even have as many calories.
I've found that if I have too much soda or HFCS, I get sleepy and drowsy, and just need to lay down for awhile. Might be the blood sugar thing, but I've never had this effect, at least nowhere as intense with anything else.
Other than soda, the most common sources of HFCS will be either condiments like ketchup and barbeque sauce, certain sweet spreads like strawberry jam, and certain pancake/waffle syrups. However, it's very easy to identify varieties of the aforementioned without HFCS. It would probably be best if you minimize HFCS to almost nothing at home.
You can have small quantities of HFCS, so no point in freaking out if you're with friends at a restaurant or something, and the ketchup there has HFCS in it. You can even have the occasional soda, but you don't want to bloat with soda.

I just drank over a liter in one go, and the drowsiness is intense for sure. I do however feel stuffed--the pleasurable "really full" feeling. I think that doing this regularly might not be best, but it was fun!
You drank over a liter in one go????????
Oh Lordy
While the stomach can stretch up to 2 - 4 liters, the average person can fit 1 liter before their stomach starts revolting.
You just drank over 1 liter of carbonated fluids. And based on our previous conversations, you have not trained your stomach for this.
Soda bottles and cans are under a lot of pressure because of the gas infused into the soda. When you add gas to a liquid, it escapes. However, if you put it in a container that prevents the gas from leaving (like a soda bottle or can) it creates pressure. On top of all that, the warmer the gas is, the more it wants to expand. The human body is much warmer than room temp soda.
With all this in mind, drinking a liter of soda will expand your stomach far more than a liter in capacity. Even more so if you drink it in one go. You haven't given the gas much time to escape, so you get a lot more stomach expansion.
This was posted an hour ago, so hopefully you're fine. But doing things runs the risk of you making yourself sick. And that is to say, nothing of the sugar high followed by the sugar crash.
Please stay safe.
