Caffeine, while not as potent as alcohol,

Mostly decaff (never tea) because the caffeine was affecting my heart as I tried to go to sleep. But, yes, the first of the day I allow one coffinated coffee. And only ever instant, which as we all know has less caffeine than tea. Yes, Yes, filter coffee has five times the caffeine than instant.

The addiction of caffeine is evident if you ever tried not drinking coffee. Headaches by 11am would be normal. Decaff avoids that................. Eventually.
