oh no! what a crappy time to get it!! Do you have a light case? (full on cases can keep you bed ridden for a month or more so I hope its not that!!)
I got mono my freshman year of college, but it was a relatively light case. I was stuck in bed for a week, but after that I was feeling slightly better. However, I was told that I couldn't drink alcohol for at least six weeks and I also had to be careful bc my spleen/liver area def stuck out for quite awhile. Even a few months after i'd be winded walking up and down stairs or going for long walks.
Talk to your doctor about these things especially if you'll be walking a lot on your vacation! Also.. tell BF to watch out cause he may get it too from smoooching!
