Hi Jen!

Welcome!
Wow 8 miles thats awesome! Yeah your symptoms sound alike the the induction flu and it varies from person to person however I don't know anyone who's flu lasted over a week so bare through it, it will get better.
I must say I do munch on the bars from time to time and if you browse the section in the walmart or supermarket where they sell them it tells you on the back of the box whether you can have them during induction.
However, don't take my word for it...use caution. I think Bonnie's response was correct.
Good Luck were all here rooting for you!
