the pain is sharp and it's very low in my gut. 

so, it's either in my intestine - which is what i thought at first - or in my bladder. if it's in my bladder, the beets are the most likely culprit, unfortunately, and i'll have to take them out. but, if it's in my intestine, it could be total fibre, and i'd be more likely to take the carrots out first.

i'll have to do the experiment.

it's diet-related, clearly. i'm not sick - it's what i'm eating.
