I am a firefighter and I work a two day on, four day off schedule. I am having trouble sleeping the night before I go on shift and both nights that I am at the firehouse. Which product that you guys offer would be best to help me with a Better sleep while I am at the firehouse. As well as allowing me not to be groggy when I have to make split second decisions and work in a high risk environment right after waking up for a call? Also, would I be able to take these products for those nights specifically instead of nonstop?
