Viagra may aid jet-lagged travelers, study shows - Yahoo! News

Adult male hamsters given Viagra, also called sildenafil, recovered from jet lag up to 50 percent faster than hamsters that were not given it, the researchers said. The scientists stopped giving the hamsters the highest dose they had been using in the experiment due to a certain side effect.

Why do I imagine this "certain side effect" somehow involves a poor little hamster whose feet can't touch the cage floor?
