Why does coffee makes me irritable but caffeine pills dont same amount of caffeine?
I think I know why.
“Higher habitual coffee consumption was associated with higher insulin sensitivity (1) and a lower risk for type 2 diabetes (2–6) in diverse populations. In contrast, short-term metabolic studies showed that caffeine intake can acutely lower insulin sensitivity (7–9) and increase glucose concentrations (10–15).”

Coffee contains a lot of chemicals besides caffeine. Maybe one, several or a combination of those chemicals is having a negative effect on you for whatever reason.

I think its dropping my blood sugar as I feel the same as when I dont eat carbs for a long time. I just had oatmeal with honey and bananas, no more agitated or irritable.
