I have experienced very positive benefits in terms of anxiety/depression on Lexapro, but due to persistent and horrible gastritis, I have switched to Sertraline, which so far has been horrendous in terms of having increased anxiety and depression. Rather than do SSRI musical chairs to find one that works, does anyone recommend GeneSight testing to determine which on to try next? I guess has anyone done GeneSight and found it helpful? Thanks in advance!
