May I suggest that you remain on your normal dose of escitalopram, and discontinue the dothiepin first? Two reasons for that. One is that you will be able to experience the escitalopram as monotherapy. And the other is more pragmatic. You will have fewer adverse effects during withdrawal if you remain on the SSRI. You should probably anticipate some rebounding. Problems sleeping, for example. Listen to your body, with respect to the pace of withdrawal. The more gradually you taper the dose, the less likely it is that you will suffer adverse effects.
