Morning sickness

Im 7 weeks pregnant.. My morning sickness already started at 6w5d. I noticed that I always started feeling sick during evening.. I cant even eat a real meal during day. I would only eat saltines cracker, drink selzter water w lemon flavor and lemon ice pop... I havent take my pretnalvitamins for two days because i cant take it w empty stomach.. Ugh how can I start eat a real meal so i can take pretnal vitamin again.. Also im using mama sea band wrist.. Ehh not really working that great.. Any tips?? I miss real food!!!
