BOOM!
I was diagnosed because of high enzymes. My ALT was 225. It had always been the same since I started getting annual physicals at age 50: 45 +/-.
My PCP said that wasn't uncommon in people who liked to drink alcohol-regularly, like all the time.
So, after the 225 wake up call, I quit drinking. A month later, the ALT was 125. Another month: 90. Another two months: 50. The next year's physical: 38.
So, my liver enzymes came down, but very slowly due to HCV.
Knock out the bug...
BOOM!

It definitely is not a "magical journey" into the vigor and optimism of my younger years feeling.
But, if I get a good night's sleep, I generally feel as good or better than I have felt in years. No illness so far this school year either. That's simply incredible for me. The past decade, it seemed like I had, or was getting over, a cold or sinusitis the whole time.
Some nights I sleep great. Some nights its like my mind won't "shut off" and the sleep sucks.
Probably age or, as my mother would say, something I ate....
