I am currently at 2.5 mg of Lexapro. I am on my 7th week of tapering off. I also take Omega 3, Lecithin and a multivitamin to help with the withdrawal symptoms. The only thing I am currently having is symptoms of feeling like my heart is racing in the evenings about 4:00 on. Is there something I should be doing to keep this from happening. I do drink a lot of diet coke and was thinking about just drinking tea. Any suggestions.
