Week 14 | Nausea is back.

I have "mild hyperemisis gravidarum" according to my practitioners, because I've only needed to go to the emergency room a couple of times. I lost 15 pounds over 2 weeks (10-12), but was able keep food down starting about 10 days ago. Unfortunately about 4 days ago I started to throw everything back up again. I was told that if I couldn't maintain calories in the second trimester I'd need either home care (which involves a port and drips in my room), and/or hospitalization. I really want to avoid both. Has anyone else had these issues, including a spike in vomiting after a lull? Any advice is appreciated.
