I prefer spinal dislocation for dispatching my feeders. I nearly gassed myself the first time I tried CO2.
Were you using the vinegar and bicarb method, or an actual regulated canister?
I have NEVER had a problem with regulated canisters - it's quite easy to work out how much gas you're using and not create so much that you gas yourself.
