No appetite

Few weeks ago I could eat absolutely everything and never get full. Now the nausea has hit and every type of food is gross to me. Sometimes I get a craving and I get it but after first bite I just want to spit it out. I haven't vomit yet but I keep getting so sick that I go to the toilet and just stare down the bowl and nothing comes up 🤣 Anyone else have this problem? I hope this doesn't last long 😥
