incidentally, is seroquel the only drug you are taking or along with antidepressants. because yes it can trigger mania if you reduce the dose all of a sudden. in fact nobody can tell with certainty because with BP1 one is more vulnerable to becoming manic. This occurred to me, i reduced my seroquel and was on an AD so i got manic which lasted for 8 months. If not for the cessation of the seroquel i might have not have turned manic. Of course perhaps yes perhaps no
i am with IL, cutting it and still sleeping well then it's ok. but if you are using it to gain stability and away from psychosis, anxiety, then you will get irritable again. Still 2 tablets isn't big dosage.
If the Seroquel is being used as a mood stabilizer yes. You could ask your psychiatrist how to adjust and titrate it as to avoid sedation or if that doesn't work what are other available options.
