Alcohol
In a few cases, muscle spasms and twitches could be the result of excessive alcohol consumptions. When you drink, alcohol is absorbed into the blood and carried to other body parts, including the muscles. Studies have shown that heavy drinkers can experience structural changes in their skeletal muscles and muscle twitches. There are 2 reasons for this. Firstly, alcoholic drinks can have a dehydration effect. Secondly, alcohol can increase the buildup of lactic acid. This substance often occurs in the body after intense exercises and causes muscle soreness and spasms. [5]
