Helli MS and welcome!
I agree with trying your doctor's method...and seeing how you do. To my understanding, Sertraline is one of the easier discontinuations, so hopefully you won't run into any difficulty.
Well done with the hard work towards your recovery thus far! If you'd like to check out our Resources at the top of the main forum page here for great material to add to your tool belt...please feel free.
Post with us anytime for support and encouragement too. We understand, care and support is key.
