Nausea causing me to eat more?!

I'm now 7 weeks pregnant and I've noticed since I've been experiencing nausea that if I force myself to eat (even though I'm nauseous) that it will help the nausea go away for a few hours. I now eat as soon as I wake up and every 2-3 hours throughout the day. It's very very different from how I used to eat when I normally skipped breakfast and had 1-2 big meals a day! I feel like I am eating way too often but I have to to keep my nausea under control. Is this normal?
