Evil corn

Second PB tonight - last week I ate corn on the cob - delicious late summer treat. After my .3ml fill on Friday I ate corn again tonight - about 1/8 of a cob plus one chicken kebab stick and OUCH - sliming and PBing (without much to show for it) for half an hour - nasty, evil corn! I know it's one of the fibrous foods I was warned about but as I hadn't had a problem last week I didn't anticipate one tonight - oh so wrong! Still, at least I know the fill did something!
