Am I unlucky or unlucky?

Went back to work yesterday, almost fully healed. But guess what? I'm down with fever again. My last night's sleep is in the bursts of 6 minutes each since 2am until I woke up at 6 just now. Must be the effect of 240 mg pseudoephedrine HCl. Never had incidents of tachycardia and insomnia before.... sad....

If I would like to say what causes my fever, I think it's lack of sleep...
