Nauseous

Can someone kindly give me tips or advice to handle being nauseous. I’m 10 weeks and I’m so nauseous it’s all day everyday. I wasn’t like this with my son I had morning sickness and tbh I rather have morning sickness then being nauseous all day everyday. Eating is such a problem, my husband has bought me a big box of crackers from Sam’s and ginger ale. Such a hit or miss sometimes it helps or make it worse. I hardly eat and that worries my husband and I, OB-GYN isn’t really worried since I’m a bit overweight
