The insomnia 😳 is killing me 😩

I was on diclegis (unisom/b6) for my first pregnancy for nausea and I guess that helped w any insomnia I may have had. Very little nausea w this baby 🤗 so I’m not taking anything, but the insomnia is so horrible! I toss and turn all night, and then when I do fall asleep in the wee hours I toss w incredibly vivid dreams that are not pleasant usually. 😖 I want to try unisom but have a 1yr old that still wakes at night that I need to tend to and I’m afraid I will be too drowsy. Any other mamas out there in the same boat or similar?? So so tired!!!!! 😩
