I get massive hangovers. I reserved an IV for two days in a row in advanced. Everyone is obviously affected differently. My first day I'd rate my hangover at a 7/10 and after the treatment it was out down to a 4/10 which is a decent improvement. The next day I'll hangover was an 10/10 and was put down to about a 6.5/10. All of the employees were very friendly. I used the royal flush package both times. People with regular hangover symptoms tend to see even better results than me, but it was still very helpful.
