I use a French press and grind my beans. It's a little more effort but makes a big difference in taste. I like darker roasts and I add nothing to it. Strong and black, two mugs every morning. One of my favorite ritualistic practices I must say. Caffeine doesn't affect me at all, I could drink...
I'm a big cheese person. Calcium is good for the bones. Whey protein I haven't had in years since my Navy days which was a decade ago. Just good ole fashioned meat person now
If I was to go back I wonder if I'll have to do basic all over again. Don't feel like doing that again. As far as restlessness do something that spikes your adrenaline like drive fast climb a cliff or go skiing whatever you enjoy
