Is anyone else experiencing extreme nausea?

Im currently 6 weeks pregnant with my second baby. This pregnancy so far has been really hard on me. I'm so nauseous I can barely eat. When I do eat, it's not much and doesn't help. I haven't been able to do much with my 2 yr old daughter because I am just so sick. I've been feeling like "lazy tv mom". 
​My first pregnancy was pretty easy. I was sick for a few weeks after I was 3 months pregnant, and that was it. 
​This time around I am just nauseous all day and into the night. It's a terrible feeling.
