I was diagnosed with "it could be mono" in college by the quack shack. My immune system has been nowhere near as good as it once was since then. When I had "it could be mono," I had NO energy, to the point that getting up and going to the bathroom down the hall felt like I had run a double marathon with two people strapped to my back. Every single part of me hurt. Light was the devil's creation. If I sat up, the room spun. I almost failed that semester because class was out of the question for a good week. When I first went back after it, I nearly passed out in the bathroom after making it out of the lecture hall.
Whatever it is Hulky has, I hope he gets better soon.
Along that same note, take care of you before him. You can't help him if you've worried yourself into a corner or a sickbed. You can't enjoy your honeymoon if you're sick from worrying over him.
