so i've visited my friend twice now, he lives up in the San Carlos CA hills, and i live in Redwood City, so we're not terribly far from each other. i like to hang out with him whenever i can, especially since he's moving soon. but EVERY time i go to his place and sleep, i wake up with a sore throat and a headache. i don't feel like crap BEFORE i sleep, no matter how long i spend there. but after i sleep for any length of time there, i just wake up feeling terrible. my roommate thinks i'm allergic to something there, but my only KNOWN allergy is Penicillin. the two places arn't really different eaither, the only major difference is that his Girlfriend has a chinchilla, but if i was allergic to it, then i'd feel like crap BEFORE i went to sleep right? this hasn't happened ANYWHERE else i've been, and i've been around...
