Hey Old Crow - given your rant I really think you will like the book I mentioned earlier - the author takes a stand very similar to the one in your rant - including a section on why not to trust the experts all the time. As for feeling lethargic - in my case that only lasted about a week and then one day I woke feeling like I could run up mountains and still have energy to burn, but like you said everyone is different and you know your body better than anyone else so trust in how you feel. Happy travels on your journey!
