big floating head.

in the past i was against taking medication to make myself feel better when i'm sick. well i am suffering from some unknown sickness that makes my head feel like it is going to explode... some sort of head cold i'm sure. so wanting to try to get some stuff done today i took some cold and sinus drug hoping for the best. all it seems to have done is make my head seem like its floating and make everything feel like it may not be completly clear. it no longer feels like it may explode but then again i don't know if i can feel my head.... which brings me back to the question, is it better to feel like crap or to feel nothing and not be able to think clearly.... hmmm which is better?
