insomnia
"I was prescribed diclegis by my OB for extreme nausea and vomiting during pregnancy. Diclegis is not covered by insurance so I researched what it was and it's basically unisom and Vitamin B6. Now the active ingredient is what is in the sleep tabs, not gels. The gels have diphenhydramine so if you are using this review to help ease nausea during pregnancy, make sure you are buying the sleep tabs. Anyway, I take one tab at night (Check it is the right dose  doxylamine 10mg) and it totally works. I don't wake up feeling nauseated at all and I sleep through the night. I do feel a little groggy in the AM, but it's hard to tell if it's from the pill or pregnancy in general. Upon further research, I discovered that the tabs were originally so designed to help with nausea. Hope this helps!"
