Hyperemesis Gravidarum?

Anybody else have this? How did you know? My first appointment isn't until the 29. However, judging by all the research I've done on 'morning sickness' (or in my case 24/7 sickness) this sounds like what's going on with me. Just wondering how many others have experienced this and what your symptoms were or how you dealt with me. Any advice/opinions/input would be appreciated.
