Nausea remedies?

Is
I've been dealing with nausea for the last couple of days but last night it got worse. I looked up to see if I could have chamomile tea and it said to limit to like two cups. Anyways, even if I try to eat I feel like I can't pass anything. I have trouble falling asleep too because of it. Any suggestions on what can help get rid of it or at least make it tolerable? 😰
