Well! Haven’t I been foolish! Last night I drank. Most of a bottle of green tea. I got these huge bottles at the dollar store and thought, yes, instead of water I’ll drink green tea. After another sleepless night I find out that green tea has caffeine plus an L thing that boosts your alertness! Not to mention the bottles are about 3 servings.! Back to water it is. No more green tea at night for me. I am careful about my caffeine consumption. Usually just have my morning glass of chai and an occasional Pepsi, but early in the day. I had no idea green tea had caffeine! I’m always reading about how healthy it is. But moderation, not 3 servings!
