Not such a big deal, I generally top up my tires before every ride anyway so replacing the CO2 takes care of itself.
I used to use CO2 with my road bikes because it's so much faster and more convenient but my recumbent tires have a lot more volume so even a 16 gram cartridge doesn't cut it. I'm back to using a pump.
