Doxylamine / pyridoxine
nausea/vomiting of pregnancy
"As a pregnant, working mom of a toddler, this medicine is my enemy.  I would rather feel the nausea than feel like I can't lift my head off of the pillow.  I have taken just one before bed a few nights in the last week and each time I do, I feel like I have the worst hangover the next day.  I can't function.  I don't recommend to anyone unless they have their entire pregnancy to hibernate."
