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 To Make Cold-Brewed Coffee: Place the coffee in a glass jar, add the water, and stir to combine. Cover and set aside at room temperature for 12 hours or overnight.  Strain the coffee through a large-size paper coffee filter, a fine sieve, or a strainer lined with cheesecloth.
