Don't feel too odd about the question. I recall the 1st time I went through carb flu. I swear I had a dropping of the entire length of my large intestine (okay maybe slight exaggeration) but it plugged up my toilet for about 2 days. Unfortunately the plunger died; got a new one and worked on toilet that night it didn't have hope. By the next evening all "worked out" and toilet was no longer plugged w/ my carb flu remnants. But that was probably a week plus into PB. I'm sure you're normal - it's just your version of carb flu... but do up your water, some veggies perhaps but it took me awhile to realize I also wasn't eating enough fat. The fat is key - as someone mentioned - it lubes up nicely.
