Unprepared for the Marathon

I returned from the trip on Tuesday, but I have been struggling with exhaustion and severe muscle and joint pain. I am not bouncing back as quickly as I had hoped. I have been having a problem with my memory and have made a couple of mistakes with my medications because of it. Last night I was not doing well because I had mistaken two medications and had doubled up on one that I should not have. Today is fortunately a very relaxing day with my family. Overall I am very happy that I made the trip, but in hindsight I should not have taken on such a large event. It is quite disappointing to me that I can no longer do things that I had always taken for granted. I feel like I ran a marathon that I had not trained for.
