morning sickness

I need help. My "morning sickness" is terrible I have not been puking but at this rate i feel like I would like that more then this. I am in constant pain feeling like I need to puke but don't. It last all day long no relief. I just want to curl up in a ball!! This is my first pregnancy. Anything I try is not working. My sister said crackers. My sister in law said protein. At first both helped now neither does. Everything smells terrible to me making me more nauseous. Any ideas what I can do. So I can at least make it thru the work day.... Thank you!!
