Working while sick

I've been sick now going on a week and a half. Started out mild, just tired and mucle pain. Escalated to constant cough, mega sore throat, and near 0 energy.

I took one semi day off, I say semi because I still responded to slacks and emails.

My wife is pissed. She's been pushing me to take sick days. Especially since we have unlimited PTO.

It's not that I'm discouraged from taking time off at all. My boss is all about taking advandage of the unlimited PTO. Most departments do. I don't.

This month, I've got 3MM in my pipeline likely to close plus multiple in person visits I have to prep for. I have to be on top of everything to make sure these deals come through. My personal sales method is very much relationship based so I try to make sure I'm as involved as possible.

I know I'm not the only one that does this. In fact, of all professions, I would assume sales is the one profession that works through illness the most.

Any tips on how to give my immune system the kick in the ass it needs? Have a client dinner in 6 days and I don't want to show up coughing.
