I have been on Celexa 9 months. Except for some initial side effects of dry mouth, tiredness, and headaches, it been excellent at reducing my anxiety. However, I have gone from 10 to 20 to 30 mg over the nine months. And now I am waking up anxious again. I am worried about hitting the 40 mg maximum dose, and not having anywhere to go. It took me years to try this drug since I dislike taking any drug at all. My heart rate is already normally about 55 bpm, and I don't want to reduce it to much less, either. Has anyone had the same experience? Has anyone maxed out at 40 for a long length of time?
