Yes coffee makes me feel very irritable and even if I drink in the morning I will not sleep well that night. It also makes my chest tight. I was on the pill for a very long time and just went off 6 months ago and haven't had coffee since. I drink green tea in the morning (it's not high in caffeine) but I never notice anything. Even if I have more than one cup of tea I don't feel as if I have had any caffeine at all so I guess no to that. What is the correlation with the birth control?
