I was on Lexapro for 1.5 years at 10mg. Upon discontinuing the medication I entered a state of constant dysphoria and brain fog. I also have the classic brain zaps and excessive sweating but I can live with those. It has been three months and I have slowly been getting better, but still suffering from debilitating brain fog and concentration issues. Has anyone had a similar experience and did it eventually go away (if so in what time period)?
