It depends.

If you are religious about refilling your CO2 cylinder when the high pressure gauge begins to decrease (indicating that no more liquid CO2 remains in the cylinder and only gaseous CO2 is left), then you will not experience EOTD.

Alternatively, if you want to run your tank all the way down to zero, then a dual stage regulator will allow you to do so.
