Severe nausea at 8weeks

Hi ladies 
I know were all in the same boat and feeling rather rough at the moment but is anyone being kept awake with the constant feeling they're going to be sick? I haven't slept properly for days and already felt exhausted before this started! 
Then during the day I continue with the feeling and can't bear to eat anything 
I know it will be worth it in the end but I just feel like my body's been taken over.
