No relief in sight 😖

I have had very little nausea the past 10 weeks. Now, I'm out of town for work and I have been SO sick for the past 3 days. I can't eat anything. I finally got some grits down last night. Today, I've got a terrible headache and I think it's because I haven't had anything to eat. I've tried ginger ale, soda water, preggo pops, crackers... Idk what else to do. I still have 3 more days until I fly home but I can barely make it out of my hotel room. Any suggestions??
