The Rozerem made me tremendously agitated and performed exactly what I needed it to do! My pulse rate was racing, and I was worried and anxious. I tried it four times and each time the result was the same. It is definitely not something you would want in your system if you are trying to relax. If you experience symptoms such as nervousness, irritability, insomnia, or anxiety when taking rozerem, you should probably stop using it immediately. These can be signs of a serious medical condition called "allergic reaction". Rosuvastatin is also known to cause liver problems and abnormal blood cholesterol levels. Rosuvastatin is used to treat high cholesterol and some other conditions such as heart failure, diabetes, and rheumatoid arthritis. It works by reducing the amount of fat in your blood while increasing the level of protein in your blood. This changes the ratio of fats to proteins which helps control blood pressure and decrease the risk of heart disease and stroke. The most common side effects of rosuvastatin include nausea, diarrhea, abdominal pain, headache, and muscle aches. If you experience any of these symptoms while taking this medication, contact your doctor immediately.
