Not only have I heard of it I have been dealing with it for the last 4 years.... I take Celexa 20mg 1x qd for my PMDD and it has been a life saver for me (no more death wish for me once a month) - I increase the Celexa to 20mg 2x qd during my period.

Sarafem is also good for PMDD if your insurance will cover it.
