Hey jmevac! Sorry for the delayed response. I didn't think I'd be on here again, thought I was getting better, ugh, it's back! Epstein Barr is very real, I was diagnosed a couple yrs ago at the local clinic. Doc told me I had mono when I was a teenager (I'm 40 now) every couple months or so I get so tired, swollen glands, body aches, severe vertigo etc. Epstein Barr is part of the herpes family, and like herpes, it never goes away. Some people have flare ups, some don't. I hope this helps .god bless.
