Does alcohol plays a role in increasing or worsening muscle cramps?

Yes, indeed. Alcohol leads to dehydration & hypoglycemia both of which can cause muscle cramps. If you're using alcohol, be sure to stay well hydrated & eat frequent small amounts of food to stave off the hypoglycemia.
Muscle cramps +booze. The answer summary required I find a shorter word than "alcohol" to fit with "muscle cramps." lol. Alcohol has a mixed effect on muscle cramps. Ingested alcohol, particularly in the form of red wine, has both short term and long term effects on blood circulation, and muscle cramping. A moderate amount of alcohol can help relax muscles. Excess could disturb calcium +magnesium and cause problems.
