ZzzQuil

Has anyone taken or asked their OB about taking ZzzQuil? I went to the store to get some for my husband because he hasn't been sleeping well. I picked up the bottle I have bought before and noticed that another bottle said "New Alcohol Free". I took it before pregnancy and several weeks ago bought a small 6oz bottle and took 1/2 doses (only took 1 full dose) on occasion when I couldn't sleep. I didn't even THINK about it having alcohol in it. It does and now I'm freaking out that I've harmed my baby 😩
