I am changing from Citalopram 5mg to Valdoxan (Agomelatine) 25mg. After five days of being moody but manageable but now on Day 6 have nausea and dizziness. This feels exactly like side affects from abruptly stopping Citalopram and am wondering if it is safe to take 5mg Citalopram to stop feeling so lousy. How long could these side affects go on for if I decide to just work through them?
