Lex symptoms and conditions

I have been on Lexapro for a few years now but just until recently have I experienced these side effects that I thought was something serious. But after reading all these comments I feel reassured that its caused from the Lexapro.Head rushes that make me dizzy, and making me sick to my stomach(causing major anxiety) . Another term I have read it head zaps, also true. Hot flashes one time while at work and Im only 30 years old. Major hunger all the time. I rally think my coworkers think Im crazy but not knowing what is making you feel crazy will cause you to panic. My husband has always told me that antidepressants were bad but haven't really notices until now. Im going to try and wein myself off of Lexapro and replace it with exercise. Has anyone else tried to do this?
