On Saturday I need to run 3 miles as fast as I possibly can. I was wondering if taking Glutamine tonight and tomorrow night will help my running. I figure that my Glutamine levels are low because I've been required to stand for at least 5-6 hours every day since monday, and yesterday I probably was standing 10 hours (the standing is because I have band practice 9am-5pm which is a lot of marching and standing plus having to go to work which is all on my feet).
