Hawaii Weather in March, April, and May. What is the weather in Hawaii in March, April, and May? The winter months are generally thought of as the rainiest times of year in Hawaii, but actually, in my experience, March and April are the rainiest, although I have been through droughts during this time period too, so anything can and does happen.
A common cause of stomach irritation from drinking green tea is its caffeine content. Green tea is not fermented like black tea or oolong tea, so typically it has a lower amount of caffeine, but it can still cause an upset stomach.
Green tea is a caffeinated beverage and may cause side effects such as rapid heart rate, upset stomach, restlessness, anxiety, insomnia and tremors. If you drink green tea regularly, your body may grow dependent on caffeine and you may get withdrawal symptoms such as irritability, drowsiness and headaches if you stop. Caffeine content varies by product, but green tea from one major brand contains about 35 milligrams of caffeine per brewed bag.
