Low acid energy drink?

[cantdrv55]

I used to dig coffee but the acid turned my stomach so I switched to tea. Well now the Chinese teas I love is starting to eat up my gut too. I still need my morning and early afternoon pick-me-up so I'm thinking about drinking sugar free Red Bull. I've tried it a couple of times before and it was gentle on my tummy but that was a few years ago. It did give me wings though.

Do you know of a low acid caffeine drink that tastes sort of OK?

I try to stay away from energy drinks, but my favorite is HiBall

caffeine pill and a bottle of water. Done!
