I have been on 100 mg of Zoloft for 8 months after a several years of prolonged stressed leading to depression. It has been a life saver. I feel like I have my happy, balanced life back. No weight gain, no anxiety, no mood swings. However, I do have problems recently with my jaw. I feel like I have TMJ. I have jaw pain and my bite doesn't feel right. I also have very vivid dreams, so vivid I sometimes have to stop during the day and ask myself did I dream that or was it real when the dream pertains to daily living. I am wondering if I need to cut back now to 50 mg.
