Stomach Aches Come and Go

I woke up in the middle of the night last night with abdominal pain.  Then it woke me this morning as well.  Now I'm feeling fine.  It comes and goes, so I just need to ride it out. 
I just started working on Dr. Schubiner's 28-day program last night before going to bed, so perhaps I have resurrected some childhood pain in the process.  I plan to continue with the program one way or the other.  Time to deal with the skeletons in the closet!
