Cataclysm Druid - how do you make sure you re-cast in time

Fellow cataclysm druids - especially the ones on console, how do you make sure you re-cast Cataclysm before it ends?

I have enough cooldown reduction so I do have around 5 to 6 seconds window to re-cast, but between running around, picking up loot, dropping rubbish loot, looking at minimap, checking headhunt progress, etc. I find myself too often miss the re-casting window and have to reactivate the Xan ruin effect, super annoying.

My solution so far is to holding down the button all time, but my finger gets tired.

So what do you guys do to always re-cast in time?
