@c531994e the 1st time we did the loop around Sisters my husband got sick about 14 miles out. Similar to your symptoms except with high fever. He didn’t get better by morning so slowly walked out. We came back the next year with extended days and had a fabulous experience. Theres no shame in turning around. Take good care of yourself Andrew. I do hope you are feeling better. 

 @c6f53033 Thank you! I’m packing my bag as I type this and about to pack my tent. Heading home to spend time with my wife and recover.
