And yes you are not alone...
You are lucky you only started at week 8. Mine was around week 6 all the way till around week 12.
They usually will tell you to eat small meals rather than 3 big meals.
I understand how you feel and I was like that too. Totally miserable and apart from going to see gynae and work, I was practically rotting at home..
If you are the type who prone to have gastric like me, always have something to eat beside your bed when you sleep. I have cereal so if I wake up feeling hungry in the middle of the night, I will eat. Or before you get up, fill your stomach first before waking up.
