Morning sickness question

This may be a weird question, but ever since MS hit me I feel nauseous all freaking day. I just moved to a new town and I need to get a job and start making money but I literally don't know how I'm gonna be able to do it when I can't even stand up for 15 minutes in the shower I just feel so sick I have to sit down. So far I haven't thrown up, I feel sick to my stomach all day and I gag like I'm gonna throw up whenever I cough or brush my teeth, but so far no puking. Do any of you ladies feel better after actually throwing up?? I just am wondering if I should stop trying to hold it back and just let myself puke if thatll mean I'll feel better for the rest of the day?
