That's a tough question. One member suggested fish oil, and that is something that might help. You can treat the stiffness and soreness directly with over the counter medications like advil. If it persists more than another week, you may want to see your doctor, and as a last resort go back on very small doses of celexa to see if that changes the symptoms, and then gradually wean from them which should be much, much easier that what you have been through.
