Citalopram to Dosulepin

[UrbanMark]

Hi there,

I've been on Citalopram for about three years now.
Because my sex drive has been extremely dampened to the point where I can't be bothered at all. My GP has given me a prescription for Dosulepin and has started me on a Citalopram reduction course.

Thing is - Do I start taking the Dosulepin while I'm still taking the Citalopram or do I wait until the Cit is out of my system?

Thanks
