I've started taking Seroquel XR to compliment Seroxat for anxiety. I've been on about 75mg (taken at night) for a couple of weeks now and I definitely notice an improvement in my anxiety which is good. The side effects appear to be tiredness and slight weight gain. I'm wondering does anyone have experience of taking this for anxiety for a lengthy period of time? Does it remain effective at the lower dose and how are the side effects? I'm hoping that the side effects will go!!
