Had some nasty chronic headaches last semester, always around noon each day. I would take a Tylenol generic for it, it would go away after a few hours and return in full force the same time next day. After a few visits to Student Health (they're not real doctors, just nurse practitioners, but checkups are free and the pharmacy is dirt cheap) I was able to stop the headaches by gradually taking less and less of the Tylenol generic. Apparently the main ingredient in Tylenol can actually CAUSE headaches when the drug is leaving your system. Whatever had originally caused the headaches had disappeared, but the withdrawal from the pain meds perpetuated the condition until I was able to gradually wean myself off of them.
Also took sick last semester with a small bug; had a high fever for 24 hours but then it went away. Onee-chan caught the swine flu, but we quarantined her off from the rest of the family and avoided catching it ourselves, and she bounced back pretty quick.
