Honestly? No. I've tried tickler files (both paper and virtual) and what ends up happening is I rarely put things in them, then forget to check. What I do now is put date-specific events on the calendar and, if necessary, make a note about where the supporting materials are on the calendar reminder. I have so few paper items, if I have something paper like tickets or a wedding invite, I put them under a magnet on the fridge. Otherwise, I scan it and it goes into a digital file.
So it's sort of a simulated tickler, but I don't have an official tickler - just another thing to check.
