Any suggestions for preventing fatigue?

[Guest guest]

Does anybody have any suggestions for preventing or reducing fatigue due to

activity?

Next week, I am going to the Equine Affaire - tons of horse related shopping and

exhibits at the fairgrounds - woohoo! However, it means lots of walking on

cement and asphalt, with places to sit in between. Last year, I wore myself

out; almost couldn't get into my friend's SUV because my legs and lower back

were so tired and sore. This year I want to be smarter about this. I am going

on a day when there will be smaller crowds, so there will be less standing

around. Obviously, I'll wear my most supportive and comfortable shoes, take my

trekking pole for balance and support, and I will make sure to take plenty of

breaks.

Would it benefit me to take Tylenol or Advil before the pain starts? Does

drinking more water than normal do anything to help? Is there anything else I

can do?

Thanks!
