Horrible all day morning all day long!

Soooo I'm only 6weeks pregnant and this morning sickness is taken its toll on me:( I have never had morning sickness before,so I feel terrible unless I'm sleeping and unfortunately I can't sleep allday:( I've called the dr and he says I'm fine just eat small snacks every hours,ugh but that's impossible! I've tried ginger,sprite,crackers and nothing has helped...my mom pretty much told me to suck it up,it can't be that bad!! I'm like it's that bad when u constantly got to throw up after eating or drinking,hell even just feeling nauseated is hard enough! Please ladies give me anything that's helped yall:)
