I hope my experience was an isolated incident, but it was not great. They were very kind when I walked in and super helpful, but the actual service was pretty bad.
The nurse first tried to put the IV in my right arm (where I always get blood drawn, IVs, etc.) and could not find my vein. So she moved the needle around (which when you're already a little nauseous is not exactly pleasant). She said she found it and started the fluid. I immediately felt the worst burning sensation and looked down at my arm and there was a golf ball sized lump under my skin. She pulled the IV out moved on to the other arm.
She had a hard time in my other arm too but finally found the vein. After the treatment I didn't really feel that much better and I wasn't really that hungover. What made me more nauseous than anything was the feeling around in my arm.
My arms were both so badly bruised. They still are and it has been a few days since the treatment and I never bruise from IVs.
I probably wouldn't come back to this place, there are a lot of other options in Las Vegas.
