Due to my intermittent fasting. My drinks are water and black coffee most of the time.

Never looked into that. But it's yummy.

Ran for years. I found chocolate milk after helped with muscle recovery.

I dont run due to peripheral neuropathy, but to recover from walking I take either decafeinated tea or sometimes the brazilian made nescaffe extra forte/extra strong. This is made in nescaffes factory in Sao Paulo and is a lot stronger than the US or European versions.
