morning sickness help

Liv
I'm seven weeks now, and just started feeling insane morning sickness. Yesterday as I was leaving work I couldn't drive, I had to call my boyfriend to pick me up. I couldn't drive to my second job, he had to take me. 
This morning I just finished eating and seconds later I threw everything up (good bye omelette I was craving like crazy).
Is gravol okay to take? Are there any other good things to help with the upset tummy?
