Sleepless nights... Tips? 💤💤💤

Does a pregnancy pillow helps you sleep better? Or just sleep? I'm 15w and I can't sleep!!! I've been like this since 8w. I try not to sleep during the day buy it does not seem to help. I go to sleep 2 hs after dinner and I'm on Diclegis for my morning sickness, which I take at bedtime. I'm exhausted...  Tips? Anyone
