Psychiatric medications are Degenerative as therapies in many cases… Meaning your body will become immune and being that every product out there maxes out in dose eventually, you may have to change them throughout your life as they come out with new ones. *WHich is the reason they come out with new ones and higher doses and time release. Like Prozac, once people were left horribly dependent upon it and they were all maxing out their does, then VOILA they created the once weekly time released 90mg dose. And all was right with the world once again.
