Alright I'm just too damn tired to read thru all the replies, I never did get to sleep last night, a slight fear of like worms crawling out of my rear end and sleeping alongside me or something. I'm damn tired and gonna get to sleep.
Yes, went to the doctor. Apparently a stool sample wasn't necesary, they have one medicine to treat all gastrointestinal worms: vermox. I'm only supposed to take it for 3 days, that seems kinda strange, I'd like to stay on it for weeks just to make sure everything's gone, but apparently that's not the way it works.
Oh, and if you're curious, the next time I went to the bathroom was like 12 hrs later after holding it in in case the doctor needed some (doh!), and I didn't even bother looking in the toilet, I just flushed every 30 secs.
To those who were grossed out: my apologies. I hope you get worms so it helps you grow some thick skin and a spine

j/k, of cource, I wouldn't wish this horror on most people.
time to pop a pill and get my arse to sleep. g'night AT
