Is dizziness during treatment with Escitalopram normal?

Hi, I take Escitalopram almost 2 years, dose 20g. I have terrible dizziness almost every day. I don't know if I've been taking them too long because all the other depressive symptoms have gone away. Only those dizziness that I also had before taking the pills. I do not know whether to continue the treatment or whether it lasts too long. Misza say that dizziness weighs me throughout the entire period of treatment once it is better and worse, rarely when I did not have them, but now they are quite bothersome! I feel much better, I see an improvement after the pills because other symptoms have gone. Is it that is, that it is not completely good with me and I still have to continue the treatment???
