Muscle twitching, also known as muscle fasciculation, is marked by small muscle contractions in the body. Your muscles are composed of fibers, tissues, and nerves. When a nerve is stimulated or damaged, it may cause your muscle fibers to twitch. Many twitches experienced in your body are common and may go unnoticed.
Update: you no longer need to hack cold-brew coffee. Try a cold-brew coffee maker! Mix 1 1/3 cup coffee grounds with 8 cups cold water. Be sure to choose good coffee- crappy coffee grounds make even crappier iced coffee. {This is my favorite decaf coffee.} Stir and place in the fridge overnight. In the AM, straining the liquid out of the coffee grounds. I find it easiest to throw a coffee filter on top of a strainer and let it do itâs thing.
Decaf brewed coffee is a better bet, only containing a little caffeine, at 3-4 mg per cup. Iced tea contains 70 mg per 12 ozs (2-4 large 12 oz glasses is safe per day) and brewed tea contains 20-90 mg in 8 oz. Check the labels on tea to find out the exact caffeine content for your specific tea. Hidden sources of caffeine.
