With Jas I was physically sick a number of times until around 20 weeks when it stopped. With Sophie I felt sick all day, every day until around 18 weeks but was never actually ill. I found keeping nibbling at light, healthy snacks kept it at bay a bit but I did get tired of constantly eating!
Hope you feel better soon
BTW, apparently it's a sign of a very healthy pregnancy if you feel sick so said my MW
