CAME OFF SERTRALINE 100mg straight over night taper 1 to other 10mg Lexapro . 1 week in 15mg Lexapro now 14days and my anxiety is ramped to max , I have been on the med before with a faster response , do you think that second time around may take a lot longer or even not work at all , I am hoping to reach 20mg Lexapro that more than the last time I was on it only 10mg but that pooped and would not respond to increase , so I want the increase to go in fist time to help failing response HELP
