Wrong. Espresso does not have the B12 which is the ingredient that makes it last more than half an hour or so.

B12 and Taurine. Without Taurine it doesn't work. But if you are prone to kidney stones stay away from that.

I don’t know about Taurine. There is none on the B12 labels and it works quite well.

I am prone to kidney stones from long before I started the B12. The first time when I was in agony and it took me an hour to rise from the bed my MIL suggested, no, required me to take a home remedy that she swore works every time. Drink six cans of Coke in a 2 hour period and follow up immediately with a can of asparagus. So I did it. By the time I finished the asparagus the stone (stones?) was gone. I have administered the operation thrice over the following 7 years. Once I had to repeat twice and actually passed a stone which wasn't pleasant. I guess the others just dissolved in the Coke.
I hate Coca Cola.
