For me it isn't nausea but just lack of hunger and then not thinking about eating while hiking.Once you get on the switchbacks last thing I am thinking about is eating.It is one foot after the other. I am known to get nauseus when my blood sugar is low. I wonder if some of the stomach nausea is not really related to low blood sugar due to high energy output?I had no problem eating at Trail Crest but I ate very little between Outpost and Trail Camp and nothing on the switch backs.
