Triathlete/marathon runner and agree elquis destroys muscles and causes a run down feeling. Never napped in my life now after long run or bike need a nap, other issue I have with it is feel cold and have chills. Looking at getting off of it and going to low dose aspirin. Many on it are having issues like what people on statins experience. Some on statins have a statin induce form a myositis wonder if elquis does the same thing.
