To answer the question, you need many years of stable spiritual routine with the specific aim of healing your body, mind, and soul. I am afraid the solution is more complicated than doing x for y amount of time, but instead a bit more individual route has to be found. Here I would advise to learn as much as you can about this path and seek Gods in your life. In the meantime, if you are on medication (and you need it to be a stable individual among your peers), keep taking the medication as you have been instructed to do. If you learn about the medication, find how it affects you specifically, and you know yourself well enough, you can opt in the route of gradually lowering the needed amount. Actually, if you do this with the doctor, even better. However, in some cases that is not a viable option and you need to do things yourself, which brings me back to the above point of knowing yourself and what you are doing as it is very important in life in general. For more specific advice you need to give more specific details.
