I'm in hell!!

Y'all. Y'ALL!!! This is awful. I've been nauseated my whole pregnancy. I mean from week 3 forward. Today, starting at 4 AM, that nausea turned into pain and vomiting. But I'm not vomiting food...just bile. My dinner from last night stayed down. Guess it had been digested. But I've been dry heaving or throwing up bile and water all day! I can't sleep. I can't do anything. I feel like I'm going to die. Does anyone have any suggestions as to what to do to stop the nausea/vomiting?
