I try to focus on something else other than my T.
@DebS actually gave me a good idea (I think it was her anyway, sorry if it was someone else) about trying to remember all the people in TV shows or movies. If you try doing this for shows such as Once Upon a Time, Game of Thrones, or the Hunger Games, then it keeps you preoccupied. I have found that even without masking I can ignore my T provided my mind is distracted. Masking helps though, so if you are struggling it does the trick.
Hope you sleep well.
