Morning sickness :(

This time i didnt have morning sickness as long as i did with my first (week 2-3 to week 26) so far only had it this week and i havent been sick today but ive already lost 17lbs since i havent been able to eat since Saturday. Any moms out there that had morning sickness, how did you get back to eating normally. I cant remember what i did when i was pregnant the first time but i was 16 then and now 19.
