actually I tried that and found for an all day hunt that #1 they made me very "jittery" and unable to sit still, and also when I came "down" off them I was more tired than before, I found when I hunt all day (most of the time) if I feel really tired, usually about mid-day, I will just sit down and nod off for 5 or 10 min. my tree stand API grandslam mag supreme, is almost impossible to fall out of with the side bars, and I just sinch my seat of the pants up real tight when Im gonna nod off, I'd rather loose 10 min of hunting asleep, then be jittery for 3 hours and not sit still. Just my opinion.
