I make my own all natural energy drink. I too don’t like coffee much, no matter how hard I’ve tried, but also those things have a lot of chemicals other than caffeine in them.

You can buy powdered caffeine derived from green tea. I do bottling including my own sodas so I have ready access and you might have to buy at least 1 lb, which is a lot of caffeine, but it’s worth it for your health.

I don’t drink more than 200mg in a day and usually not even that much so maybe I’m at a gram a week-ish. So a lb would last me for over 8 years.

Get a jewelers scale and you’re good to go
