Of course you can fix it! What's the temperature of the keg now? If it's room temperature, the co2 will come out pretty easily. Start by taking it off of the gas, of course. Then pull the pressure relief valve often, releasing all of the gas in the headspace. It should get to a "normal" carb in a couple of days.
