Sick Again

How is it that I only got majorly sick once or twice in the first two years of medical school, yet in the last five months I managed to get sick four times? I started getting a cough about 3 days ago (pretty sure I got it from my dad, who's been coughing for a week), but despite sleeping most of yesterday and today, I still got a fever. =( I don't have a thermometer so I don't know how bad it is (probably around 100; I'm pretty sure it's a viral dz again), but when the heater's on high and I'm shivering, that's a pretty good sign of fever. =( This sucks, and I have OSCE and hospital week in the next few days, too. Not to mention Dr. RR expects me to know everything about diabetic drugs and dosages by the time I return to his clinic next week; how am I going to be able to rest, recover, and study all at once? *sigh* One thing at a time, crescendo.
