don't road trip in your first trimester

Jill
Word of advice... do not do a road trip in your first trimester!! We did a 14 hour drive to myrtle beach and stayed for a week.  We just got home last night and I'm paying for it! I was nauseous and has a bag in my hand the entire drive home.  The nausea continued into today and I'm just exhausted. 
I can't find relief for the nausea... help!!
