Congrats, ToxDoc! I think quitting was the smart thing to do. I’m no expert on long term fasting or much of any of this, but the combination of being so cold you can’t do anything to warm up and you skin issues (including the thing with bites not healing) make it seem to me like you were running short of some critical nutrients.
And I think the digestion issues you’re talking about are much better to deal with today and even tomorrow than on your trip to your conference!
