7 weeks 3 days pregnant

I am 7 weeks 3 days, and from one week, i am feeling worst. I cant eat anything properly, cant drink water, even if have sip, i feel like throwing up. I had nausea medication, but that makes me feel crazy. That makes me very sleepy i cant even stand or do anything and its not helping much now in nausea or making me eat something. I feel very dehydrated. I get burps often and have acid reflux. I eat and drink only enough to survive. I start my work early morning 6am. Please help me fellow mamas if you have any tricks to overcome this or any suggestions for staying hydrated while you having nausea.
