Hey. Theres this medicine called Provigil, that was issued to soldiers in Iraq during the war. It helps keep you awake, aware, and alert. It has average side effects..nausea, nervousness, anxiety and insomnia. Which is what most pills do when they keep you awake. The most frequently reported problem was a light to mild headache. My point in this, is has anyone had problems staying awake at those big airsoft operations? Would this help anyone at the 40 hour SF test? If anyone knows more, that would be great. Thanks.
