After three months of taking generic brand Lexapro, I started experiencing extreme dizziness and vertigo. Basically,I increased the daily dosage from 10mg to 20mg, after which these symptoms began almost instantly. I stopped taking the medication 2 months ago, and yet these feelings of dizziness have not subsided, to make matters worse, these feelings are usually accompanied by extreme anger and irritability. Of note, I was on the medicine for around 7 months, and have taken the medicine in the past. Also, whenever I eat or drink alcohol, the dizziness is much worse. Is this Seratonin withdrawal?
