I had two different ones fail on me this morning. I don't know if there is a lifespan to the cups in which my soft drink will not dribble out of where the lid screws on and down onto my shirt and I have exceeded that time. But I am tired of not have the cup function as I expect. (And I'm sure the lack of caffeine in my body makes a difference too.)

So does anybody have some recommendations or hacks to make this not be a problem any more?
