OF COURSE: Check with your doc.
BUT:
As a casual observer, I noticed you say you have had "VERY FEW" hangovers, especially since your bout with CMV.
As, such, I offer the (slightly less exciting, and more realistic) suggestion that you are GETTING OLD.
Hangovers when you're 50 are WAAAAAAY, WAAAAAAAY different than when you're 21, or 35. They last 24 or 36 hours, instead of 12.
So, (IMO) it's possible you're experiencing the effects of being a normal guy. Of course, there's never any harm done in talking to your doc..
Good luck!!!
