I’ve taken a half tablet (12.5) around twice a week while in 2nd trimester. It’s the only time I get 8 hours straight. I was recommended to only use the 25 mg tablets and split them in half. I still feel weird about it but it was recommended by my doctor. I also use 8 sheep’s organic body lotion on other days which helps but not the same as unisom ! Anyone take unisom or have other suggestion/alternatives? I didn’t have insomnia with my son. I am hitting the 20 week mark with new baby and have had insomnia most of this pregnancy. At times I’ve woken up every two hours and can’t fall back asleep- I am reading a lot when I can’t sleep which seems to help. In the first trimester I took nothing - This is driving me nuts !! Lol
