Thanks so much for all of this help.

I think the first thing I'll try is some Tylenol PM, start there, and keep a food diary in the next month to identify trends with when I ride/what did I eat the few hours before.

I also bought several different kinds of meal bars yesterday that I'll be trying out during rides in the coming week.

I am most likely not pregnant, but that is a good suggestion. I've had this problem for several months now, so this is likely not the problem.

I will also check in with a doctor as soon as my health insurrance kicks in in July--It's very unsettling to have to wait this long but I'll keep you updated.

Thanks for the well wishes and advice!!
