Just leave the anti-perspirant (or deoderant) also at work. I bought a travel size spray and solid from the local store. Since I take a shower at home in the morning and use some deoderant before leaving, I rarely need to use more when I get to work. Maybe when the Summer goes into full swing I'll need some extra. I also wash my hair and face in the bathroom sink after I arrive at work. Also helps me to keep a little more "minty fresh."
