15 mg celexa

So I’ve been on 20 mg then back down to 10 because of the brain fog but then started feeling anxious all the time on the 10 like it wasnt enough so now I’m on 15 and I’m finally actually feeling now I’m not all zombie feeling I guess lol but still have brain fog and feel more weird but I think it’s just my body getting used to the 15mg now so anyone experience feeling weird to talk to friends and family ?
