"Morning Sickness" help


So I am 7 weeks and 4 days pregnant. In the last few days my sickness has gotten worse. I get nausea at all times of day. Especially at around 3 am. I try to force some crackers down but it is so hard to even swallow each bite. If I don't then the sick gets even worse. Are there any better ways to deal with the "morning sickness"? It has been 3 days, straight, of constant sickness.
