No appetite

its my 17weeks and i still having morning sickness. less appetite for food. Cant even smell of my husband eventhough he has already taken a shower. ☹ Every night I have to go through different kind of tummy symptom(e.g. heartburn, indigestion, gastric) and i will ended up with vomitting before i can really sleep and by than its already 2am-3am. I was warded twice for hyperemesis gravidarum. When I went for my appointment and asked for my gynae advise he will answer "its normal".What should I do?
