Hey, you guys don't know me yet, but I plan on showing up to the session on Saturday.
Anyway, mono is an ugly thing. It affects every person slightly differently. My mom was out for a month and a half with it when she had it in high school. I had it in my senior year of high school and was out for a solid 3 months with minor symptoms carrying out for another 3 months after. I've also heard of people only having it for a few weeks.
As for the healing process and mono, there isn't much to be done but wait it out. Sleeping and resting and reducing stress will expediate the process slightly as it allows your body to focus more energy on keeping you well. My own suggestion for you is to rest whenever possible, start drinking a lot of water, try and get your hands on some vitamin supplements, and just generally try not to push yourself too hard. If you're going to work on something, take breaks often.
And as far as the contagiousness of mono goes, if you've had it before, it's really really hard to catch it from someone else, if not impossible....like chicken pox.
Well, there's my two cents.
