Thank you for your query.
I do not think you're psychosis
is caused by the drugs, but rather symptoms of the disease you are being treated for. This means that you are not responding to the treatment as well as one would hope. It is not unusual for someone with your condition to take a combination of three drugs, and the combination you mention is an acceptable regime. I suggest that you try by taking the Nortriptyline
for at least one month. If you are still not happy, consult your doctor to re-look you're treatment.
The most important aspect of treating your condition is for the patient to comply with the treatment , and have a good feedback system with your doctor.
I trust this information helps you.
