So I'm 7 weeks today & am battling nausea and the deep hunger pangs that I know are acid. I vomited last night after taking iron pill. No pain or anything else just the nausea, smelling foods can set it off also. I estimate my calories intake has been below 400 each day. I've been working hard to get liquids and protein. Today I've had 30 g of protein and few bites of egg salad & 17ounce of water.

Your iron might be the cause of your nausea. I take 2 Fintstone Complete vitamins per day. They have iron in them. Also, the hunger pangs....well, I don't believe anyone who tells me that they "forget to eat". I always have hunger. I did find, however, that taking one Zantac every morning cut down on the "noises" that my stomach had been making. For acid, Alkaseltzer Heartburn chewables help a lot.
