Has anyone had success with lexapro. I have been on it about 3 weeks and I don't see much improvement. I am still depressed and very anxious. I am on other meds for the anxiety also. I also have depersonalization/derealization with this. Sometimes I have strange sensations in the left side of my head that make me feel funny all over. My depression seems to be localized to the left side of my head if that makes any sense. I would appreciate any info. Thanks and God Bless.
