if it's possible to have hyperemesis graviduram without ending up in the hospital and without throwing up all the time?

I'm almost 9 weeks and I have terrible nausea all day everyday and drinking water makes me sick. I barely drink anything all day. I usually have like two cups of juice and tiny sips of water equaling to about only 1.5-2 bottles of water per day. I feel very guilty because of this. But water makes me so sick. So how come I haven't ended up in the hospital? I am able to eat once or twice a day but not much. Is that maybe why I don't end up in the hospital because I'm at least getting some sodium from food? Idk but I'm miserable guys. I have thrown up twice in this pregnancy so far. Oh I also forgot to mention I am on zofran twice daily but my nausea still comes through even while on the medication. Please is there any advice for how to get in more fluids??
