Mate I am already in that boat shooting 5iu at bedtime and 5iu early am, I HATE napping in the day - makes me all spun-out and grumpy for at least an hour after I wake up but the last few weeks I am having to arrange my diary for the day so that I can come home at lunchtime and pass out for a few hours, otherwise I am nearly falling asleep at the wheel - it's the only thing that may prevent me from continuing this GH run indefinitely.
