Welcome to the forums.
Whenever I have to change any of my medications, I expect my GP or Psychiatrist, or whoever is prescribing the medication, to tell me how to go off one med & then how to introduce the new med.
I also ask about what I can expect to experience, likely side-effects, the best way to take them, what to avoid while taking them, etc.
If I might feel some unusual feelings, sensations, then I can feel prepared for that & be patient with myself about any such odd feelings I might have.
I also will keep talking to whoever prescribes the meds & tell them how I am feeling. That way they can monitor how the medication are or aren't working for me.
I hope that helps.
