Puking all the time

Hi mummies, I’m 7 weeks pregnant and I haven’t been eating well. Everytime I thought I’m gonna be full from eating a meal, I’ll just puke everything on the last few bites. Poly doctor refuse to give me anti-nausea pills but managed to get some from a tele-consult doctor. I have to take the pills on an empty stomach but i rarely get nauseous when I’m not eating unless there are triggering smells. Any advice on this? I’m hungry all the time now :(
