I think eating well is easier on systems over-taxed by POIS, like the liver and others.
I've been on a diet for about 6 months.... more for general health reasons than anything. I will have to work at 4000 meters (12,500 ft) in the mountains on a mining project soon, so preparing for that.
But it's the Chilean "4th of July", and I had a whole week off, eating barbeques, drinkng wine and beer.... and every day about 9 PM I was feeling like crap. It's a heavy strain on the liver, especially after I've been treating it so well. For the first time in about a year, I had chalky pee in the morning, after sex the night before.
I took my viagra and the POIS is barely present, but more than usual.
You don't realize the load that bad diet puts on you, until you clean up for a good while. Back at healthy eating tomorrow!!
