At the tip of your tongue?

Losing things and trying to find them can be draining and time consuming. 

When you can't find the keys in your bag, you pour out its contents. 

When you can't find something you think was in your pocket, you pull it out from your sides inside out. 

But when you can't find the right words when speaking or writing,pulling out your tongue and shaking it out from your head will not do the trick. 

And the more you panic, the longer it takes.
