Caffeine is liquid anxiety. It gives u that UP you need to get going, but the coming down time is anxiety riddled in most people. I have been caffeine free sine 1990 - and if I accidently am given a soda with caffeine in it - I get the shakes (mild), but I know what has done it so it does not upset me. I would try to get off the caffeine and of course no alcohol with those meds! I don't know alot about the meds side, but I have heard people just starting on Lexapro felt like their innards were shakin'. Check with a pharmacist about that cocktail - they usually know more about cocktails than the prescribing Doctor ! Good luck !
