Cold/allergies during pregnancy

Diane

25 weeks pregnant. Either allergies have hit me super hard or I have a cold. Stuffy nose, sneezing, coughing a little. I tried taking a Zyrtec last night before bed and I slept great and could actually breathe. It’s a 24 hour pill so can’t take another until tonight so wondering if there’s anything else that could help me during the day? I work so can’t be anything that will make me sleepy. I’m just feeling miserable.
