How did I do Vegas before Hangover Heaven? I love this place. I first came here a few years back after doing some research on jetlag and found that B12 shots can help. I came her after 2 days of partying and after 10 minutes I was ready to go all over again. I now visit every time I'm in Vegas. I recently visited after my bachelorette party for the Myers IV drip. I needed something to get me back on my feet for my wedding - it did the trick! I felt brand new. Try this place.....you won't be disappointed. This place will take your 4 day hangover down to a couple of hours.
