I hope you have been back for a check since, i have to be tested every 3 mths now. My metabolisism was running at non-human levels, around 500% higher than a normal. (like running a marathon everyday) I was hospitalised and quite ill for a while.
Now it's slowly swinging towards the same direction as yours. I really have had to make some major adjustments to my routine over recent years.
I am still in very good nick, always have been... I wouldn't like to think where i'd be without that solid foundation I have to help drive me.
Keep tweaking things, you'll find what works for you sooner or later.
