I've learned to use caffeine in a healthy way. I never drink more than one cup of coffee and I always take a few days off from caffeine before drinking it again. I only use it for migraines and severe pain. It helps me with my pain. It doesn't take much just a small amount. My doctor actually taught me how to use it. I have a rare brain disorder and the caffeine is helpful to keep my heart from slowing down, it also helps my migraines at bay alongside my medication because it can be caused by lack of blood flow to my brain from anxiety and I hold my breath too much. Caffeine helps me to breathe too. I have been suffering from the migraines lately and I found out about sugar free caffeine drinks that help me without giving me too much caffeine or sugar. I am very grateful for my healthcare providers too.
