GMAT Quantitative Section | data sufficiency - keep forgetting minor details from stem

I'm sure many share the same issue.

Say the stem says: x and y are both integers. Even if I write it at the top of the page - I always forget to refer back to it when I solve DS questions (because I'm in a rush, obviously I forget). And often this is key to choosing among some of the answer choices.

I was wondering if anyone had any cool strategies to not miss these kind of bells and whistles? do you write them next to the equations or just on top? Or something else?

Thanks!
