I have a friend that is 11 weeks, she's going through it rough right now with HG, anyone have any suggestions , she can't keep anything down and is nauseous 24/7, so it's been hard for her to eat, she's got a pump that gives her meds to help but I wanted to get other opinions and suggestions from other mommies that have been through it, I too had HG and have given her my advice , and things that helped me but everyone is different, so just curious if there's things that I can't tell her that I didn't try!?
