Either the sauna or a Colon Cleanse (which I doubt it was the colon cleanse) caused me to have trouble digesting animal proteins.
It wasn't the sauna. If the Colon cleanse contained Psyllium, or Bentonite clay They both swell in the intestine. If you don't drink enough water with Psyllium, it will turn to a concrete like substance and block the bowls. The sauna requires a lot of water as you are sweating water, so doing them at the same time probably wasn't a good idea.
