Did your Psychiatrist warn you about any possible
side effects beforehand? This is something any Psychiatrist should do, if not, be sure to ask! Or if you don't have any attachment to this particular one, and aren't against finding a new one, it is another option. Remember, you're the customer!
Are you seeing any progress with the Seroquel? If you're not, ask your Psychiatrist if you can't try something else.
