Morning sickness!

Help I'm 2 months and 1 week prego today and i work 8 hours a day in Dunkin donuts.... The smells don't really bother me but we get super busy I don't have time to eat until more than half way through my shift ... My stomach starts to hurt then I get nauseous.... I have tried to drink a lot of water but it doesn't seem to help... Do y'all have any suggestions or advise???
