Great post, Myscha! I feel for you... 

The last place I stayed at was a completely ecologically sustainable permaculture property. This meant that not only did we grow our own food and compost all waste, but we also recycled everything....including our own pee and poop. Bring on the buckets! One for poop (which got buried and eventually turned into soil), one for pee (which was diluted and used to feed nitrogen fixing trees). No toilet paper was used - we had to get creative, and the act of going in two different buckets was a challenge to be sure! 

And after two months there, I still had immense problems dealing with the buckets (thank goodness for my gracious and willing boyfriend who saved the day). It was all I could do to function with them.

But enough about poop. 

All this to say that after living a life on the extreme end of being environmentally conscious and sustainable, returning to "civilization" afterwards was difficult. Part of me was revolted at the level of consumption going on everywhere (and still is), yet another part of me went on a similar shopping spree to yours....a feeling of being deprived of so many conveniences I was used to turned me into a temporary maniac. 

So I look forward to your future posts, and lessons learned. I hope to learn a few lessons from you too!
