my dr, started me on 20mg lexapro, and ive been on it for 4 days, but everytime i take it, its freezing but im very hot, and dripping in sweat, i also get very tired. and have dry mouth, and i have low sex drive, and cant really feel anything. is this normal, should i stop taking the meds, its not helping with my anxiety either but it has helped a lot with my depression? or does it have something to do with me being on depakote with it as well
