I make fizzy water at home. How many times can a 2 liter bottle be used with a carbonation unit?

I doubt there's a better answer than "until it fails"...
Seconded - there is no good way to estimate the lifespan/built up stress in the plastic nondestructively.

I do know that without proper sterilization a bottle will only last (food grade) once or twice.  I also know that many sterilization methods break down plastic bottles, so they have a limited lifespan in that sense too.
