Visions in my head

After the bout of food poisoning, the thought has crossed my mind that I've been infected with some sort of terrible parasite.  I highly doubt this is the case, but my digestive habits are much changed from what they were.  I'm trying to abide by the bland diet a friend suggested but I'm really, really tired of rice.  As most of you know by now, I share a little too much at times.  However, I can't help telling you that each time I "go" I check for something parasite like in the bowl.  I don't know if I'm expecting round worms like what I've seen cats have or some sort of gigantic tape worm.  I know it's  all in my head, but we've all seen the awful stories on tv about parasites. 

Again, sorry if I've made your breakfast/lunch/dinner roil around in your stomach, but these are the things I think about.  It's important that you understand how my brain functions or well, lack thereof.  :)
