Morning Sickness

Hey ladies, so I'm 10 weeks and 4 days today! and my doctor wants me to go into the er for dehydration and be tube fed, my morning sickness is so severe I have done nothing but lose weight and I do nothing but sleep and sleep on the toilet seat just waiting for my meal to come up :( I'm miserable I've tried everything! They put me on diclegis and it's made me 10x worse and made me 10x more tired :( I've tried pickles, lemons, I've been eating small meals, I've been staying away from fast food I've been eating mostly fruits and veggies, ive tried ginger ale and ive tried preggy drops and just nothing is helping. I need help! I don't wanna have to go to the er an be tube fed I want that to be my last resort, any other moms have this problem? And recommendations will be very helpful! Thanks xx
