I sit for about an hour, look around then stand for about 10 minutes, then sit for another hour.
The last hour I stand and try to move my eyes first then slowly only my head to look.
I dont have to look at my watch by digging under the clothes covering my wrist...it's on a velcro watchband thats strapped to my bow's riser.
If I drink anything it's during those periods when I'm standing.
