>>292721>atalso I am the exact opposite of OP. It takes me forever to get going in the morning, my bivvy is usually unpleasantly warm and humid, and I threaten anybody who talks to me with murder for the first 30-45 minutes or so I am awake. This is true no matter what I consume, how much sleep I get, or where I wake up though, it's just usually less pleasant on the trail. Once we get moving I mellow out.
