I'm similar in the morning and nightly protection for myself, family, and where we reside, including where we are at. Like Pagan/Laura stated if you start feeling some bad energy or feeling like your getting tired/worn out...I'd say put it up again. You'll know when you need to ask and put up protection. With practice it comes second to nature and you'll do it without barely blinking.

If your not sure it doesn't hurt to put it up again

love and blessings
