It's possible that the drugs you took have no long term effects but many alternative health professionals have found that they can be contaminated with pollutants which can cause lasting problems. Some of these pollutants are verry sticky and difficult to get out of your body so it may require several different detox protocols, liver cleansing, kidney cleansing, diet changes and protecting yourself from pollutants in our food or environment.
Sometimes when we go through a bad experience we tend to think that our problems started with that event. You might want to think back and view your life as a whole - especially ask what triggered your psychriatic problems. Recently Drs have come to realize that most psycological problems are a result of imbalances in the chemistry of the body. What caused that unbalance? It was probably not some outward problem, but some inner imbalance in your metabolism. One possibility is gluten sensitivity. A gluten free diet may help you as much as the detox and cleanses you are planning to do. It may help you to look at some of the Celiac Disease and Gluten intolerance forums and see their experiences are similar to yours.
