24 hour nausea - need advice

Since my six week mark hit, I also got hit with 24 hour nausea. I eat, I stay nauseous. I can't even think about taking my vitamins without wanting to throw up. I know I need to take them but what can I do so I can? I try salt but that lasts maybe 20 minutes max. Anyone tell me what works for you so I can try it!! Thanks in advance.
