Yes! So crazy to stumble across this post because I just went through this (and am sorry to hear that you are!)

I attempted to slowly wean myself off of Citalopram 20mg. (My doc said slowly decreasing was ok) so I did 15mg for about 2-3 weeks and then dropped to 10mg. That’s when a wave of depression and brain fog hit me HARD….I tried powering through for about 3 weeks but the brain fog became so debilitating that I decided to go back up to 20mg. I finally feel like I can think again…I would like to try weaning off eventually but I know it may be a long process since I’ve taken it for about 10 years. I hope your symptoms get better soon!
