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.
1 For example, if you have 2 cups of coffee each morning, have one instead or make yourself a cup that is half decaf and half regular coffee. 2  Brew for less. You can easily reduce the amount of caffeine in your morning cup of coffee by simply brewing it for less time.  Try herbal or decaf teas instead of regular tea.
