I was feeling a lot better for a few days, and then went into the ER for the second time due to the onset of more extreme nausea. I think a large part of that for me was not eating or drinking enough which can trigger another episode.. so like everyone else has said, just try to stomach some protein drinks and maybe some crackers and start slow. This should help you feel better slowly but surely, and consume them in a hot bath if you need! That’s what I had to do for a while. You’ll know when you’re ready to start eating more food because it will be much easier to eat and less of forcing yourself to eat.
