The first step to recovery is SLEEP!
And if you are not able to get that great night of sleep it makes all of the other steps to recovery so much more important.
Drink endless amounts of lemon water.
Other helpful remedies...
And even after the warm salt water gargle I decided it was necessary to make some chamomile tea and then add copious amounts of honey to soothe my angered vocal cords.
Do something, ANYTHING, active.
Vacations are not an excuse to drop your work out, I mean while I was in Vegas I did walk up and down the strip wearing heels, and danced in crazy high platforms - that has to count for some kind of a work out!
Jumping back into a fitness regime is hard after a few days off so to ease myself back in I did ten minutes a yoga several times of day, it quickly resolved all of my soreness and I was back to a full hour in yoga sculpt in no time. After sleeping on an air mattress and on the plane my neck was stiff and my legs were also a bit tight (from the 9 inch platforms) so I couldn't wait to get back home and start my fitness routine again but it still wasn't easy, which is all the more reason to continue your work out routine while on your rockstar vacation. But I didn't get an intentional sweat on while in Vegas... and IT'S OK. I just had to work harder to get the aches to subside.
