please be careful... Remeron is prescribed for the treatment of major depression--that is, a continuous depressed mood that interferes with everyday life. The symptoms of major depression often include changes in appetite and weight, difficulty sleeping, loss of interest in pleasurable activities, constant fidgeting or a slowdown in movement, fatigue, feelings of guilt or worthlessness, difficulty concentrating, slowed thinking, and suicidal thoughts... yadda, yadda, yadda.
We really aren't 100% sure as to its mechanism of action, but Remeron is thought to work by adjusting the balance of the brain's natural chemical messengers, especially norepinephrine and serotonin.
As far as drug interactions are concerned, I really suggest you rethink your practice of using Remeron in conjunction with other drugs (especially tryptamines). Serious, sometimes fatal reactions have been known to occur when drugs such as Remeron are taken in combination with MAO inhibitors. A good rule of thumb is to never take Remeron with one of these drugs or within 14 days of discontinuing therapy with one of them; and allow at least 14 days between stopping Remeron and taking a chemical which may acts as an MAO inhibitor.
