Does anyone else suffer from oxygen debt after tumble turn?

This is not the least of my worries in swimming, but I tend to fall into oxygen debt after tumble turns. In fact, when I keep doing tumble turns in lap swims, it is less taxing to swim 50 LCM than 25 SCY, because I have more time in 50 LCM to recover from the oxygen debt, whereas in 25 SCY, I have to do another tumble turn and fall, yet again, into oxygen debt, before fully recovering from the previous bout. Do other master swimmers out there suffer from a similar problem? How do you over come this?
