Do u feel full all the time? (1st trimester)

I'm in my 8th week. I do feel hungry just like prior 3 times a day but my appetite has been abt 0.25 portions of usual. And if I eat more I will feel like puking. If I do not eat I will have the nauseous feeling so I better eat smth light. In summary I perhaps can try to eat 6 smaller meals a day but who has so much time to prepare food when I'm working.. But this roller coaster mood everyday is draining... Will it ever pass....
