getting IV for nausea?

Molly • 35 yrs old, married in 2013. We live in Big Bear Ca. 4 and 1.5 yr old girls.
I'm only 6 weeks along. EDD nov 3. I've had awful morning sickness. I can't work, barely feeding myself, keeping food down, liquids make me super sick. I've heard of getting an IV to help.  Being in Vegas there's a ton of places here lol hangover specific, but also just vitamin infused. 
 Has anybody done it? How often? Did it help? Was it scary? Any feedback would be great
